我們使用蘋果手機的時候會發現IOS中有底部彈框效果,重底部向上彈出效果,下面是通過PopWindow來實現仿IOS彈框:
效果圖:
項目工程目錄:
1、首頁佈局就一個按鈕
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<Button
android:id="@+id/button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="點擊提示" />
</RelativeLayout>
2、設置popwindow要彈出的佈局
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="@+id/dialog_ll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentBottom="true"
android:background="#33000000"
android:gravity="bottom"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:background="@drawable/popup_window_bg"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="選擇圖片"
android:textColor="#838383" />
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_marginTop="10dp"
android:background="#ececec" />
<TextView
android:id="@+id/tv_photo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:gravity="center"
android:onClick="click"
android:paddingBottom="10dp"
android:paddingTop="10dp"
android:text="相冊"
android:textColor="#3AC0FA"
android:textSize="17sp" />
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#ececec" />
<TextView
android:id="@+id/tv_photograph"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:gravity="center"
android:onClick="click"
android:paddingBottom="10dp"
android:paddingTop="10dp"
android:text="拍照"
android:textColor="#3AC0FA"
android:textSize="17sp" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:background="@drawable/popup_window_bg" >
<TextView
android:id="@+id/tv_cancle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:gravity="center"
android:onClick="click"
android:paddingBottom="10dp"
android:paddingTop="10dp"
android:text="取消"
android:textColor="#3AC0FA"
android:textSize="17sp" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- 背景色 -->
<solid android:color="#FFFFFF" />
<!-- 圓角 -->
<corners
android:bottomLeftRadius="6dp"
android:bottomRightRadius="6dp"
android:topLeftRadius="6dp"
android:topRightRadius="6dp" />
</shape>
4、在res文件夾下創建 anim文件夾,用來彈出動畫調用,在anim文件夾下創建xml文件hide_to_bottom.xml和show_from_bottom.xml
hide_to_bottom.xml代碼:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="200"
android:fromYDelta="0"
android:toYDelta="100%p"/>
<alpha
android:duration="200"
android:fromAlpha="1.0"
android:toAlpha="0.0"/>
</set>
show_from_bottom.xml代碼:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="200"
android:fromYDelta="100%p"
android:toYDelta="0"/>
<alpha
android:duration="200"
android:fromAlpha="0.0"
android:toAlpha="1.0"/>
</set>
5、在values裏的styles.xml文件里加入代碼:
就是剛剛創建的2個動畫文件
<style name="popupwindow_anim_style">
<!-- 指定顯示的動畫xml -->
<item name="android:windowEnterAnimation">@anim/show_from_bottom</item>
<!-- 指定消失的動畫xml -->
<item name="android:windowExitAnimation">@anim/hide_to_bottom</item>
</style>
private PopupWindow pw;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button bt=(Button) findViewById(R.id.button);
bt.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
showEditPhotoWindow(v);
}
});
}
private void showEditPhotoWindow(View view) {
View contentView=getLayoutInflater().inflate(R.layout.popup_window_title_image, null);
pw=new PopupWindow(contentView, getWindowManager().getDefaultDisplay().getWidth(), getWindowManager().getDefaultDisplay().getHeight(), true);
//設置popupwindow彈出動畫
pw.setAnimationStyle(R.style.popupwindow_anim_style);
//設置popupwindow背景
pw.setBackgroundDrawable(new ColorDrawable());
pw.showAtLocation(getWindow().getDecorView(), Gravity.CENTER,0,0);
//處理popupwindow
popupwindowselectphoto(contentView);
}
//初始化控件和控件的點擊事件
private void popupwindowselectphoto(View contentView) {
TextView tv_select_pic=(TextView) contentView.findViewById(R.id.tv_photo);
TextView tv_pai_pic=(TextView) contentView.findViewById(R.id.tv_photograph);
TextView tv_cancl=(TextView) contentView.findViewById(R.id.tv_cancle);
LinearLayout layout=(LinearLayout) contentView.findViewById(R.id.dialog_ll);
tv_select_pic.setOnClickListener(pop);
tv_pai_pic.setOnClickListener(pop);
tv_cancl.setOnClickListener(pop);
layout.setOnClickListener(pop);
}
private OnClickListener pop=new OnClickListener() {
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.tv_photo:
Toast.makeText(MainActivity.this, "相冊 ", Toast.LENGTH_SHORT).show();
break;
case R.id.tv_photograph:
Toast.makeText(MainActivity.this, "拍照 ", Toast.LENGTH_SHORT).show();
break;
case R.id.tv_cancle:
if(pw!=null){
pw.dismiss();
}
break;
//點擊提示框以外的地方關閉
case R.id.dialog_ll:
if(pw!=null){
pw.dismiss();
}
break;
}
}
};
