android AlertDialog类

1）更改AlertDialog窗口大小的方法：

		AlertDialog dialog = new AlertDialog.Builder(this)
				.setTitle("Dialog")
				.setMessage("I am a Dialog!")
				.setPositiveButton("Ok", new DialogInterface.OnClickListener() {

					public void onClick(DialogInterface dialog, int which) {

					}
				})
				.setNegativeButton("Cancel",
						new DialogInterface.OnClickListener() {

							public void onClick(DialogInterface dialog,
									int which) {

							}
						}).create();
		dialog.show();
		WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
		params.width = 400;
		params.height = 200;
		dialog.getWindow().setAttributes(params);

 

2）去除Dialog边框

		factory = (LayoutInflater) mContext
				.getSystemService(LAYOUT_INFLATER_SERVICE);
		renameView = factory.inflate(R.layout.rename_layout, null);
		AlertDialog dialog = new AlertDialog.Builder(this)
				.setTitle("Dialog")
				.setPositiveButton("Ok", new DialogInterface.OnClickListener() {

					public void onClick(DialogInterface dialog, int which) {

					}
				})
				.setNegativeButton("Cancel",
						new DialogInterface.OnClickListener() {

							public void onClick(DialogInterface dialog,
									int which) {

							}
						}).create();
		dialog.setView(renameView, 0, 0, 0, 0);
		dialog.show();
