Question

我似乎遇到了一个可能很容易解决的烦恼，但我无法弄清楚如何。目标是在应用程序打开时随机输出两个不同的图像（图片：mario.png和logo.png）。它工作了很长时间，直到我尝试将默认的app图标（Image：ic_launcher.png）更改为Manifest中的新图标（Image：smoke.png）。当我这样做时，应用程序只会输出logo.png和ic_luancher.png。我尝试将清单更改回ic_luancher.png，但无济于事。任何想法？

public class MainActivity extends Activity {

private String[] Fact;
private static final Random rgenerator = new Random();
private int[] picArray = {
    R.drawable.logo,  //This actually outputs
    R.drawable.mario, //This one outputs the defualt app icon although it is not the one I want.
};

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().setBackgroundDrawable(new ColorDrawable(Color.rgb(225, 151, 51)));
    setContentView(R.layout.activity_main);

    Resources res = getResources();
    Fact = res.getStringArray(R.array.Facts);
    String q = Fact[rgenerator.nextInt(Fact.length)];
    TextView tv = (TextView) findViewById(R.id.daily);
    tv.setText(q);

    Drawable d = getResources().getDrawable(picArray[rgenerator.nextInt(picArray.length)]);
    ImageView ptv = (ImageView) findViewById(R.id.imageView1);
    ptv.setImageDrawable(d);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

}
