本文介绍了一种在Android应用中创建自定义对话框的方法。通过实例展示了如何设置对话框的布局、背景及按钮点击事件等关键操作。

	private void showDialog() 
	{
		mDialog = new Dialog(this);
		mDialog.setCanceledOnTouchOutside(true);
		
		Window dialogWindow = mDialog.getWindow();
		dialogWindow.setBackgroundDrawable(new ColorDrawable(0));
		dialogWindow.setContentView(R.layout.set_public_client_dialog);

		mDialog.show();
		
		Button cancelbtn = (Button) dialogWindow.findViewById(R.id.cancelbtn);
		cancelbtn.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				mDialog.dismiss();
			}
		});
		
		Button confirmbtn = (Button) dialogWindow.findViewById(R.id.confirmbtn);
		confirmbtn.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				mDialog.dismiss();
			}
		});
		
	}
