    </LinearLayout>

</LinearLayout>

 然后在类中直接调用就可以：

btn.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				showDialog();
			}
		});
	}
	
	// 弹出更新的版本
		private void showDialog() {
				ShowMsgDialog MyupDialog = new ShowMsgDialog(MainActivity.this,
						"标题名", "内容名称【弹出对话框】") {
					// 选择修改
					@Override
					public void doConfirmUp() {
						dismiss();
					}
				};
				MyupDialog.show();
			}
