我们先看下面的弹出框如何实现:

xml文件:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:tools="http://schemas.android.com/tools"
                android:id="@+id/title"
                android:layout_width="match_parent"
                android:layout_height="60dp" >

    <TextView
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_marginTop="20dp"
        android:layout_height="60dp"
        android:layout_marginLeft="25dp"
        android:text="@string/upgrade_content"
        android:textColor="#000000"
        android:textSize="22sp" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_below="@id/content"
        android:orientation="horizontal" >

        <CheckBox
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_marginLeft="15dp" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_marginLeft="15dp"
            android:text="@string/remind_me"
            android:textColor="#000000"
            android:textSize="14sp" />
    </LinearLayout>

</RelativeLayout>

代码实现:

public AlertDialog getEditCustomDialog(String leftText,android.content.DialogInterface.OnClickListener leftlistener, String rightText, android.content.DialogInterface.OnClickListener rightlistener) {
    LayoutInflater inflater = getLayoutInflater();
    View view = inflater.inflate(R.layout.test_dialog1, null);
    AlertDialog.Builder builder = new AlertDialog.Builder(DialogTest.this);
    if (!TextUtils.isEmpty(leftText)) {
        builder.setNegativeButton(leftText, leftlistener);
    }

    if (!TextUtils.isEmpty(rightText)) {
        builder.setPositiveButton(rightText, rightlistener);
    }

    builder.setView(view);
    builder.setTitle("A New Version is Available");
    return builder.create();
}

Dialog dialog = getEditCustomDialog("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        Log.d("TAG","<<<<left ");
    }
}, "Upgrade Now", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        Log.d("TAG","<<<<right ");
    }
});
//是否可以点击硬件的back让弹出框消失
dialog.setCancelable(true);
//是否点击弹出框的空白部分可以让弹出框消失
dialog.setCanceledOnTouchOutside(true);

我们可以在dialog.show以后通过WindowManager来改变框的大小

WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();
lp.width = DialogTest.this.getResources().getDimensionPixelSize(R.dimen.dialog_width);
lp.height = DialogTest.this.getResources().getDimensionPixelSize(R.dimen.dialog_height);
dialog.getWindow().setAttributes(lp);
