1、自定義代碼實現：
private void addAndEditBookmark(final String typeStr, String title) {
// 1. 佈局文件轉換爲View對象
LayoutInflater inflater = LayoutInflater.from(context);
RelativeLayout layout = (RelativeLayout) inflater.inflate(
R.layout.bookmark_add, null);
// 2. 新建對話框對象
dialog = new AlertDialog.Builder(context).create();
dialog.setCancelable(false);
dialog.show();
Window window = dialog.getWindow();
window.setContentView(layout);
window.clearFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
// 就是這個屬性導致不能獲取焦點,默認的是FLAG_NOT_FOCUSABLE,故名思義不能獲取輸入焦點
window.getAttributes().flags = window.getAttributes().FLAG_DIM_BEHIND;
window.setAttributes(window.getAttributes());
window.setLayout(screenWidth / 3, LayoutParams.WRAP_CONTENT);
// 3.標題內容
TextView dialog_title = (TextView) layout
.findViewById(R.id.title_bar_name);
dialog_title.setText(title);
// 4. 消息內容
dialog_msg = (EditText) layout.findViewById(R.id.input_add_string);
if ("add".equals(typeStr)) {
dialog_msg.setHint("請輸入添加的標籤名稱");
} else if ("edit".equals(typeStr)) {
String str = (String) list.get(selectedIndex).get("markName");
dialog_msg.setHint(str);
}
// 5. 確定按鈕
Button btnOK = (Button) layout.findViewById(R.id.dialog_ok);
btnOK.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
String str = dialog_msg.getText().toString();
if (null == str || "".equals(str) || "null".equals(str)) {
Toast.makeText(context, "標籤名稱不能爲空", Toast.LENGTH_SHORT)
.show();
return;
} else {
addOrEditMark(typeStr, str);
}
dialog.dismiss();
}
});
// 6. 取消按鈕
Button btnCancel = (Button) layout.findViewById(R.id.dialog_cancel);
btnCancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
}
2、對應的xml文件：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@color/white"
android:gravity="center"
android:padding="8dp" >
<RelativeLayout
android:id="@+id/layout_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/title_background"
android:gravity="center_vertical" >
<TextView
android:id="@+id/title_bar_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"

android:singleLine="true"
android:text="添加書籤"
android:textColor="@color/custom"
android:textSize="18sp"
tools:ignore="HardcodedText" />
</RelativeLayout>
<EditText
android:id="@+id/input_add_string"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/layout_title"
android:layout_marginTop="10dp"
android:background="@drawable/edittext_bg"
android:focusable="true"
android:focusableInTouchMode="true"
android:singleLine="true"
android:textSize="18sp"
tools:ignore="TextFields" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/input_add_string"
android:layout_marginTop="10dp"
android:gravity="center"
android:orientation="horizontal" >
<Button
android:id="@+id/dialog_ok"
android:layout_width="wrap_content"
android:layout_height="40dip"
android:layout_weight="1"
android:background="@drawable/btn_background"
android:text="確定"
android:textColor="@color/white"
tools:ignore="HardcodedText" />
<Button
android:id="@+id/dialog_cancel"
android:layout_width="wrap_content"
android:layout_height="40dip"
android:layout_marginLeft="5dp"
android:layout_weight="1"
android:background="@drawable/btn_background"
android:text="取消"
android:textColor="@color/white"
tools:ignore="HardcodedText" />
</LinearLayout>
</RelativeLayout>
