後臺生成

[java]view
plain copy

public LinearLayout CreateSetting(Drawable img,String _text)  

    {  

        RelativeLayout  rl = new RelativeLayout(getActivity().getApplicationContext());  

        RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(  

                RelativeLayout.LayoutParams.MATCH_PARENT,Dp2Px(getActivity(),39));  

         lp.addRule(RelativeLayout.CENTER_HORIZONTAL);  

         rl.setLayoutParams(lp);  

         RelativeLayout.LayoutParams lpiv = new RelativeLayout.LayoutParams(  

                    RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);  

         lpiv.addRule(RelativeLayout.CENTER_VERTICAL,RelativeLayout.TRUE);  

         lpiv.addRule(RelativeLayout.ALIGN_PARENT_LEFT,RelativeLayout.TRUE);  

         lpiv.setMargins(Dp2Px(getActivity(),12), 0, 0, 0);  

         //lpiv.addRule(RelativeLayout.RIGHT_OF,iv.getId());  

         ImageView iv = new ImageView(getActivity().getApplicationContext());  

         iv.setLayoutParams(lpiv);  

         iv.setImageDrawable(img);  

         iv.setId(99);//動態相對佈局必須設置id，getid才能取到  

         RelativeLayout.LayoutParams lp_tv = new RelativeLayout.LayoutParams(  

                    RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);  

         lp_tv.addRule(RelativeLayout.CENTER_VERTICAL,RelativeLayout.TRUE);  

         lp_tv.setMargins(Dp2Px(getActivity(),11), 0, 0, 0);  

         lp_tv.addRule(RelativeLayout.RIGHT_OF,iv.getId());  

         TextView tv = new TextView(getActivity().getApplicationContext());  

         tv.setLayoutParams(lp_tv);  

         tv.setText(_text);  

         tv.setTextColor(Color.parseColor("#000000"));  

         RelativeLayout.LayoutParams lp_img = new RelativeLayout.LayoutParams(  

                    RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);  

         lp_img.addRule(RelativeLayout.CENTER_VERTICAL,RelativeLayout.TRUE);  

         lp_img.addRule(RelativeLayout.ALIGN_PARENT_RIGHT,RelativeLayout.TRUE);  

         lp_img.setMargins(0, 0, Dp2Px(getActivity(),12), 0);  

         //lpiv.addRule(RelativeLayout.RIGHT_OF,iv.getId());  

         ImageView ivarrow = new ImageView(getActivity().getApplicationContext());  

         ivarrow.setLayoutParams(lp_img);  

         ivarrow.setImageDrawable(this.getResources().getDrawable(R.drawable.ios_arrow));  

         rl.addView(iv);  

         rl.addView(tv);  

         rl.addView(ivarrow);  

         LinearLayout  ll_line = new LinearLayout(getActivity().getApplicationContext());  

         LinearLayout.LayoutParams lp_line = new LinearLayout.LayoutParams(  

                    RelativeLayout.LayoutParams.MATCH_PARENT,1);  

         lp_line.setMargins(Dp2Px(getActivity(),46), 0, 0, 0);  

         ll_line.setLayoutParams(lp_line);  

         ll_line.setBackgroundColor(Color.parseColor("#cccccc"));  

         LinearLayout  ll_f = new LinearLayout(getActivity().getApplicationContext());  

         LinearLayout.LayoutParams lp_f = new LinearLayout.LayoutParams(  

                    RelativeLayout.LayoutParams.MATCH_PARENT,RelativeLayout.LayoutParams.WRAP_CONTENT);  

         ll_f.setLayoutParams(lp_f);           

         ll_f.setOrientation(LinearLayout.VERTICAL);  

         ll_f.setClickable(true);  

         Drawable ll_fd = this.getResources().getDrawable(R.drawable.myborder);

         }  

         ll_f.addView(rl);  

         ll_f.addView(ll_line);        

       return ll_f;  

    }

[java]view
plain copy

public int Dp2Px(Context context, float dp) {   

        final float scale = context.getResources().getDisplayMetrics().density;   

        return (int) (dp * scale + 0.5f);   

    }  

後臺設置高寬

[java]view
plain copy

LayoutParams lp;          

      lp=mbtn.getLayoutParams();  

      lp.width=100;  

      lp.height=200;          

      mbtn.setLayoutParams(lp);

android:background="@drawable/layout_leftradiusborder"可以不用setBackgroundDrawable提示過期了,

可以使用 ll_f.setBackgroundResource(R.drawable.layout_leftradiusborder);

LinearLayout.LayoutParams.WRAP_CONTENT與

RelativeLayout.LayoutParams.WRAP_CONTENT感覺都是一樣的效果

一：在後臺添加表格

[java]view
plain copy

public void Eidt(List<TableItem> _tis,LinearLayout popView,Activity _mActivity)  

{         

       TableLayout tl = (TableLayout)popView.findViewById(R.id.mytab);  

       tl.setStretchAllColumns(true);  

       TableRow.LayoutParams trlpf = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,  

            TableRow.LayoutParams.WRAP_CONTENT);//表格內添加的控件必須要用TableRow.LayoutParams不然調用tl.setStretchAllColumns會報錯  

       trlpf.setMargins(0, 9, 0, 0);  

       trlpf.gravity = Gravity.RIGHT|Gravity.CENTER;//相當於layout_gravity  

       TableRow.LayoutParams trlpfe = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,  

            TableRow.LayoutParams.WRAP_CONTENT);  

       trlpfe.setMargins(0, 9, 0, 0);  

       for(int i=1;i<_tis.size()-4;i++)//  

       {  

        TableItemNameValueShrink tt = (TableItemNameValueShrink)_tis.get(i);  

           TableRow tr = new TableRow(_mActivity);  

           tr.setLayoutParams(trlpf);  

           TextView tv = new TextView(_mActivity);  

           tv.setTextColor(Color.parseColor("#bbbbbb"));  

           tv.setLayoutParams(trlpf);  

           tv.setGravity(Gravity.RIGHT);//設置文字居中  

           tv.setText(tt.name+":");  

           tv.setEms(4);//小技巧文字不夠可以設置此固定幾個字符的長度  

           EditText ed = new EditText(_mActivity);  

           ed.setLayoutParams(trlpfe);  

           ed.setText(tt.value);  

           ed.setTextColor(Color.parseColor("#666666"));  

           ed.setEms(9);  

           tr.addView(tv);  

           tr.addView(ed);                                 

        tl.addView(tr);           

       }       

}

二：常用樣式設置

[java]view
plain copy

              TableRow.LayoutParams trlpf = new TableRow.LayoutParams(0,  

TableRow.LayoutParams.WRAP_CONTENT,7);  

trlpf.setMargins(2, 2, 0, 0); //left, top, right, bottom  

trlpf.gravity = Gravity.RIGHT|Gravity.CENTER;//設置layoutmagin  

         TextView staName =  new TextView(WTRes.this);  

 staName.setLayoutParams(trlpf);//添加布局  

 staName.setText(jsonObj.getString("staName"));  

 staName.setTextColor(Color.parseColor("#000000"));  

 staName.setBackgroundColor(Color.parseColor("#BCD553"));  

 staName.setTextSize(14);  

 staName.setGravity(Gravity.CENTER);//設置文字居中  

 tr.addView(staName);

package yu.activity;

import android.app.Activity;

import android.graphics.Color;

import android.os.Bundle;

import android.view.Gravity;

import android.view.ViewGroup.LayoutParams;

import android.widget.LinearLayout;

import android.widget.RelativeLayout;

import android.widget.TextView;

public class TextViewJava extends Activity {

private LinearLayout mLayout;

private TextView mTextView;

private RelativeLayout mLayout2;

private TextView mTextView2;

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

// 創建一個線性佈局

mLayout = new LinearLayout(this);

// 接着創建一個TextView

mTextView = new TextView(this);

// 第一個參數爲寬的設置，第二個參數爲高的設置。

mTextView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,

LayoutParams.WRAP_CONTENT));

// 設置mTextView的文字

mTextView.setText("這是我的TextView");

// 設置字體大小

mTextView.setTextSize(20);

// 設置背景

mTextView.setBackgroundColor(Color.BLUE);

// 設置字體顏色

mTextView.setTextColor(Color.RED);

//設置居中

mTextView.setGravity(Gravity.CENTER);

mTextView.setPadding(1, 0, 0, 0);//left, top, right, bottom

// 將TextView添加到Linearlayout中去

mLayout.addView(mTextView);

// 創建一個線性佈局

mLayout2 = new RelativeLayout(this);

// 接着創建一個TextView

mTextView2 = new TextView(this);

// 第一個參數爲寬的設置，第二個參數爲高的設置。

mTextView2.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,

LayoutParams.WRAP_CONTENT));

// 設置mTextView的文字

mTextView2.setText("這是我的TextView");

// 設置字體大小

mTextView2.setTextSize(20);

// 設置背景

mTextView2.setBackgroundColor(Color.BLUE);

// 設置字體顏色

mTextView2.setTextColor(Color.RED);

// 設置居中

mTextView2.setGravity(Gravity.CENTER);

//相對位置

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)mTextView2.getLayoutParams();

params.setMargins(1, 0, 0, 0);// 通過自定義座標來放置你的控件left, top, right, bottom

mTextView .setLayoutParams(params);//

// 將TextView添加到RelativeLayout中去

mLayout2.addView(mTextView2);

// 展現這個線性佈局

setContentView(mLayout);

setContentView(mLayout2);

}

設置可見性 setVisibility():

三：動態添加布局文件

[java]view
plain copy

LinearLayout layout;  

    @Override  

    public View onCreateView(LayoutInflater inflater, ViewGroup container,  

            Bundle savedInstanceState) {  

        // TODO Auto-generated method stub  

        layout=new LinearLayout(getActivity());  

          ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(  

                    ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT);  

        layout.setOrientation(LinearLayout.VERTICAL);//顯示方向  

        layout.setLayoutParams(params);  

        return layout;  

        //return inflater.inflate(R.layout.mytable_trans, container, false);  

        //return super.onCreateView(inflater, container, savedInstanceState);  

    }

四：動態相對佈局

[java]view
plain copy

TextView tv = new TextView(this);  

        tv.setText("高度:100cm");  

        tv.setTextColor(Color.BLUE);  

        RelativeLayout.LayoutParams tvparams = new RelativeLayout.LayoutParams(  

                ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT);  

        tvparams.setMargins(0, 0, 0,80);  

        tvparams.addRule(RelativeLayout.CENTER_HORIZONTAL);//水平居中  

        tvparams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);//在佈局底部  

        tv.setLayoutParams(tvparams); //使layout更新  

        layout.addView(tv);

lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE); 
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);

// addRule方法將按鈕佈局添加到button1的右邊
params.addRule(RelativeLayout.RIGHT_OF, R.id.button1);

lpiv.addRule(RelativeLayout.RIGHT_OF,iv.getId());

五：listview後臺設置高度，注意dp像素的轉化

定義一個函數將dp轉換爲像素

public int Dp2Px(Context context, float dp) {

final float scale = context.getResources().getDisplayMetrics().density;

return (int) (dp * scale + 0.5f);

}

定義函數動態控制listView的高度

public void setListViewHeightBasedOnChildren(ListView listView) {

//獲取listview的適配器

ListAdapter listAdapter = listView.getAdapter();

//item的高度

int itemHeight = 46;

if (listAdapter == null) {

return;

}

int totalHeight = 0;

for (int i = 0; i < listAdapter.getCount(); i++) {

totalHeight += Dp2Px(getApplicationContext(),itemHeight)+listView.getDividerHeight();

}

ViewGroup.LayoutParams params = listView.getLayoutParams();

params.height = totalHeight;

listView.setLayoutParams(params);

}

LayoutParams.WRAP_CONTENT));

// 設置mTextView的文字

mTextView.setText("這是我的TextView");

// 設置字體大小

mTextView.setTextSize(20);

// 設置背景

mTextView.setBackgroundColor(Color.BLUE);

// 設置字體顏色

mTextView.setTextColor(Color.RED);

//設置居中

mTextView.setGravity(Gravity.CENTER);

mTextView.setPadding(1, 0, 0, 0);//left, top, right, bottom

// 將TextView添加到Linearlayout中去

mLayout.addView(mTextView);

// 創建一個線性佈局

mLayout2 = new RelativeLayout(this);

// 接着創建一個TextView

mTextView2 = new TextView(this);

// 第一個參數爲寬的設置，第二個參數爲高的設置。

mTextView2.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,

LayoutParams.WRAP_CONTENT));

// 設置mTextView的文字

mTextView2.setText("這是我的TextView");

// 設置字體大小

mTextView2.setTextSize(20);

// 設置背景

mTextView2.setBackgroundColor(Color.BLUE);

// 設置字體顏色

mTextView2.setTextColor(Color.RED);

// 設置居中

mTextView2.setGravity(Gravity.CENTER);

//相對位置

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)mTextView2.getLayoutParams();

params.setMargins(1, 0, 0, 0);// 通過自定義座標來放置你的控件left, top, right, bottom

mTextView .setLayoutParams(params);//

// 將TextView添加到RelativeLayout中去

mLayout2.addView(mTextView2);

// 展現這個線性佈局

setContentView(mLayout);

setContentView(mLayout2);

}

三：動態添加布局文件

[java]view
plain copy

LinearLayout layout;  

    @Override  

    public View onCreateView(LayoutInflater inflater, ViewGroup container,  

            Bundle savedInstanceState) {  

        // TODO Auto-generated method stub  

        layout=new LinearLayout(getActivity());  

          ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(  

                    ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT);  

        layout.setOrientation(LinearLayout.VERTICAL);//顯示方向  

        layout.setLayoutParams(params);  

        return layout;  

        //return inflater.inflate(R.layout.mytable_trans, container, false);  

        //return super.onCreateView(inflater, container, savedInstanceState);  

    }

四：動態相對佈局

[java]view
plain copy

TextView tv = new TextView(this);  

        tv.setText("高度:100cm");  

        tv.setTextColor(Color.BLUE);  

        RelativeLayout.LayoutParams tvparams = new RelativeLayout.LayoutParams(  

                ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT);  

        tvparams.setMargins(0, 0, 0,80);  

        tvparams.addRule(RelativeLayout.CENTER_HORIZONTAL);//水平居中  

        tvparams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);//在佈局底部  

        tv.setLayoutParams(tvparams); //使layout更新  

        layout.addView(tv);

lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE); 
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);

// addRule方法將按鈕佈局添加到button1的右邊
params.addRule(RelativeLayout.RIGHT_OF, R.id.button1);

lpiv.addRule(RelativeLayout.RIGHT_OF,iv.getId());

五：listview後臺設置高度，注意dp像素的轉化

定義一個函數將dp轉換爲像素

public int Dp2Px(Context context, float dp) {

final float scale = context.getResources().getDisplayMetrics().density;

return (int) (dp * scale + 0.5f);

}

定義函數動態控制listView的高度

public void setListViewHeightBasedOnChildren(ListView listView) {

//獲取listview的適配器

ListAdapter listAdapter = listView.getAdapter();

//item的高度

int itemHeight = 46;

if (listAdapter == null) {

return;

}

int totalHeight = 0;

for (int i = 0; i < listAdapter.getCount(); i++) {

totalHeight += Dp2Px(getApplicationContext(),itemHeight)+listView.getDividerHeight();

}

ViewGroup.LayoutParams params = listView.getLayoutParams();

params.height = totalHeight;

listView.setLayoutParams(params);

}

後臺動態添加布局文件、控件與動態設置屬性

android 依賴工程 Android 工程引用其他Library工程

android 4.0後請求網絡android.os.NetworkOnMainThreadException

android百度地圖常用

後臺動態添加布局文件、控件與動態設置屬性

.net發送post請求的兩種方法
