我想在屏幕上显示四个自定义时钟，我尝试使用此代码

@shivang请参考此代码并输入四个时钟。如下代码所示。 请它对你有所帮助。
private ImageView img;
Handler mHandler;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Thread myThread = null;
Runnable runnable = new CountDownRunner();
myThread = new Thread(runnable);
myThread.start();
}
public void doRotate() {
runOnUiThread(new Runnable() {
public void run() {
try {
Date dt = new Date();
int hours = dt.getHours();
int minutes = dt.getMinutes();
int seconds = dt.getSeconds();
String curTime = hours + ":" + minutes + "::" + seconds;
Log.v("log_tag", "Log is here Time is now" + curTime);
img = (ImageView) findViewById(R.id.imgsecond);
RotateAnimation rotateAnimation = new RotateAnimation(
(seconds - 1) * 6, seconds * 6,
Animation.RELATIVE_TO_SELF, 0.5f,
Animation.RELATIVE_TO_SELF, 0.5f);
rotateAnimation.setInterpolator(new LinearInterpolator());
rotateAnimation.setDuration(1000);
rotateAnimation.setFillAfter(true);
img.startAnimation(rotateAnimation);
} catch (Exception e) {
}
}
});
}
class CountDownRunner implements Runnable {
// @Override
public void run() {
while (!Thread.currentThread().isInterrupted()) {
try {
doRotate();
Thread.sleep(1000);
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
} catch (Exception e) {

}
}
}
}
