仅仅须要在 XML 里面贴图即可了！注意高版本号中使用 TextClock 替代

1.MainActivity.java

package com.sweetlover.activity;

import com.sweetlover.digitalclockdemo.R;

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
	}
}
