攝即是空

基本

	private void myAlertDialog() {
		Builder MyAlertDialog = new AlertDialog.Builder(this);
		MyAlertDialog.setTitle("title");
		MyAlertDialog.setMessage("info");
		DialogInterface.OnClickListener OkClick = new DialogInterface.OnClickListener() {
			public void onClick(DialogInterface dialog, int which) {
				// 如果不做任何事情 就會直接關閉 對話方塊
			}
		};
		;
		MyAlertDialog.setNeutralButton("center", OkClick);
		MyAlertDialog.setPositiveButton("left", OkClick);
		MyAlertDialog.setNegativeButton("right", OkClick);
		MyAlertDialog.show();
	}

List

private void myListAlertDialog() {
		final String[] ListStr = { "1", "2", "3", "4", "5" };
		Builder MyListAlertDialog = new AlertDialog.Builder(this);
		MyListAlertDialog.setTitle("title");
		// 建立List的事件
		DialogInterface.OnClickListener ListClick = new DialogInterface.OnClickListener() {
			public void onClick(DialogInterface dialog, int which) {
				Toast.makeText(Basis_AlertDialogActivity.this, ListStr[which],// 顯示所點選的選項
						Toast.LENGTH_LONG).show();
			}
		};
		// 建立按下取消什麼事情都不做的事件
		DialogInterface.OnClickListener OkClick = new DialogInterface.OnClickListener() {
			public void onClick(DialogInterface dialog, int which) {
			}
		};
		MyListAlertDialog.setItems(ListStr, ListClick);
		MyListAlertDialog.setNeutralButton("cancel", OkClick);
		MyListAlertDialog.show();
	}

自定義

AlertDialog builder;
	private void showDialogLayout(Context context) {
		LayoutInflater inflater = LayoutInflater.from(this);
		final View textEntryView = inflater
				.inflate(R.layout.dialoglayout, null);
		builder = new AlertDialog.Builder(context).create();
		Button OKBut = (Button) textEntryView.findViewById(R.id.okbut);
		OKBut.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				Toast.makeText(Basis_AlertDialogActivity.this, "DialogBtn",
						Toast.LENGTH_LONG).show();
			}
		});
		Button BackBut = (Button) textEntryView.findViewById(R.id.backbut);
		BackBut.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				builder.cancel();
			}
		});
		builder.setView(textEntryView);
		builder.show();
	}
