android setcontentview错误

Question

我有三个布局。各背景图片 但是，我遇到了一个问题。

当我使用setcontentview切换到第三个布局时。

会导致。

java.lang.RuntimeException: Unable to start activity

我不得不认为可能是因为背景图片的问题。

我将两个布局文件的背景更改为相同。

确实能够解决这个问题。

但当我在ImageView底部时。

并放置在原始的第三个布局背景之上 将导致out of memory error

最后怎么做 要实现这一点，我需要三个布局背景图像吗？

我想到的压力只有10k仍然有这个错误。

内存消耗是基于图像大小不是基于绘图的容量？

第一项活动：

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.op);
        Runnable runnable=new Runnable(){
            public void run(){
                Intent intent = new Intent(MainActivity.this, dm.newbie.myhoust.indexx.class);
                MainActivity.this.startActivity(intent);
              }

            };
            Handler handler=new Handler();
            handler.postDelayed(runnable,3000);
    }


}

indexx.java

public class indexx extends Activity {
int num;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_main);
    Button boy=(Button)this.findViewById(R.id.button1);
    boy.setOnClickListener(new OnClickListener(){
        public void onClick(View v){
            num=2;
dr();
        }

        private void dr() {
            Bundle bData = new Bundle();
             bData.putDouble( "pag",num);
             bData.putDouble( "secc", Integer.parseInt(
                   ((EditText)findViewById( R.id.editText1 ))
                   .getText()
                   .toString()
                   )
         );

            Intent intent2 = new Intent(indexx.this, dm.myhoust.run.wait.class);
            intent2.putExtras(bData);
            indexx.this.startActivity(intent2);

        }
    });
}

}

wait.java

public class wait extends Activity {
     Double num2;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.infd);
        Bundle bData = this.getIntent().getExtras();
         Double num1 = bData.getDouble( "secc" );
         num2 = bData.getDouble( "pag" );

        Runnable runnable=new Runnable(){
            public void run(){
                Intent intent = new Intent(wait.this, dm.myhoust.run.ringring.class);
                Bundle bData2 = new Bundle();
                bData2.putDouble( "pag",num2);
                intent.putExtras(bData2);
                wait.this.startActivity(intent);
              } 
            };
            Handler handler=new Handler();
            handler.postDelayed(runnable,(long) (num1*1000));
    }

}

ringring.java

public class ringring extends Activity {
     Timer timer = new Timer(true);
     MediaPlayer mp;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ring);       
         ImageView callman = (ImageView)this.findViewById(R.id.imageView1);


  //If the background is not replaced before use this instead   
         //ImageView callman2 = (ImageView)this.findViewById(R.id.imageView2);
//callman.setImageResource(R.drawable.bg);


         callman2.setImageResource(R.drawable.sf);
        Bundle bData2 = this.getIntent().getExtras();
         Double num1 = bData2.getDouble( "pag" );
         if(num1>1){
             callman.setImageResource(R.drawable.s1);
         }
         Timer timer = new Timer();  
         timer.schedule(new timerTask(), 5000, 5000);
         mp = MediaPlayer.create(ringring.this, R.raw.skype);

    }
      public class timerTask extends TimerTask
      {
        public void run()
        {

        mp.start();    
        Vibrator myVibrator = (Vibrator) getApplication().getSystemService(Service.VIBRATOR_SERVICE);
        myVibrator.vibrate(3000);
        }
      };

}

由于背景不同，导致此错误：

这是使用imageview方式替代背景错误：
