我用 android studio 0.1 创建了一个启动画面,但是当我在我的手机(nexus s)上用 USB 调试模式测试它时,图像没有显示.. 为什么?
这是 MainActivity
package com.example.splash;
import android.content.Intent;
import android.os.Bundle;
import android.app.Activity;
import android.os.Handler;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Handler x = new Handler();
x.postDelayed(new SplashHandler(), 7000);
}
class SplashHandler implements Runnable{
public void run(){
startActivity(new Intent(getApplication(), Main.class));
MainActivity.this.finish();
}
}
@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;
}
}
这是主要的
package com.example.splash;
import android.app.Activity;
public class Main extends Activity {
}
这是 Splash.xml
< ?xml version="1.0" encoding="utf-8"?>

android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" android:background="@drawable/splash">
