我正在制作一款应用程序,可以在随机的地方onCreate上显示数字时钟。我希望该应用程序只需每分钟重复该功能。有没有人有任何想法如何实现?
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView textView = (TextView) findViewById(R.id.digitalClock1);
Random r = new Random();
int x = r.nextInt(350 - 100);
int y = r.nextInt(800 - 100);
textView.setX(x);
textView.setY(y);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

使用Handler
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
Random r = new Random();
int x = r.nextInt(350 - 100);
int y = r.nextInt(800 - 100);
textView.setX(x);
textView.setY(y);
}
}, 1000 * 60);
