用安卓写的程序检查没错误但是模拟器运行不起来

开始测试了下没问题，但是再mainActivity里加入了这段程序就无法打开了import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;

public class LuckyPanActivity extends Activity {
/** Called when the activity is first created. */

private LuckyPan mLuckyPan;

private ImageView mStartBtn;

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(new LuckyPan(this));

mLuckyPan=(LuckyPan) findViewById(R.id.id_luckypan);

mStartBtn=(ImageView) findViewById(R.id.id_start_btn);

mStartBtn.setOnClickListener(new OnClickListener() {

public void onClick(View v) {

if(!mLuckyPan.isStart()){

mLuckyPan.luckyStart();

mStartBtn.setImageResource(R.drawable.stop);

}

else{

if(!mLuckyPan.isShoudEnd()){

mLuckyPan.luckyEnd();

mStartBtn.setImageResource(R.drawable.start);

}

}

}

});

        }

}
去掉这段程序一点毛病都没有，加上这段就打不开，这一段到底该放在哪，我试着放在SurfaceChanged里面一点用都没有甚至无法读取我在main。xml里面的名字

把报错的信息贴出来才好判断，你的new LuckyPan(this)是什么？

和上面同问， new LuckyPan（this）是什么写法

你的LuckyPan用传值进去，或者设置id吗，你可以try,catch一下，把LuckyPan直接打印出来

1——》setContentView(new LuckyPan(this));

at com.my.lin.LuckyPan.onTouchEvent这里报了空指针，是不是设置事件的时候没获取到控件导致的？
