您必须使用初始屏幕活动,然后您必须从该初始屏幕活动开始您自己的活动。
这是splashActivity 的代码。
public class SplashActivity extends Activity {
private int splashTime = 3000;
private Thread thread;
private ProgressBar mSpinner;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
mSpinner = (ProgressBar) findViewById(R.id.Splash_ProgressBar);
mSpinner.setIndeterminate(true);
thread = new Thread(runable);
thread.start();
}
public Runnable runable = new Runnable() {
public void run() {
try {
Thread.sleep(splashTime);
} catch (InterruptedException e) {
e.printStackTrace();
}
try {
startActivity(new Intent(SplashActivity.this,YourActivityName.class));
finish();
} catch (Exception e) {
// TODO: handle exception
}
}
};
}
这是activity_spalsh.xml文件的代码.....
