Android 如何解决：二进制XML文件行#8：错误膨胀类

我的应用程序包括在用户说话时移动图片。我已经这样做了，但是当我试图为我的应用程序设置一个图像作为背景时，我遇到了一个问题。我正试图使用xml文件来实现这一点，但是我得到了一个错误：膨胀类。有人能帮我吗？ 提前谢谢

xml类中的第8行是：

<com.example.prova1.MoveBalloon.DrawBalloon
        android:id="@+id/drawBalloon1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="182dp" />

我试图与xml连接的MoveBallon类是

package com.example.prova1;


import android.app.Activity;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.util.AttributeSet;
import android.view.SurfaceHolder;
import android.view.SurfaceView;

public class MoveBalloon extends Activity {
 Bitmap balloon;
 DrawBalloon myView;
 float x,y,sensorX, sensorY;
 SensorManager sm;
 Microphone mic;



public class DrawBalloon extends SurfaceView implements Runnable {

 SurfaceHolder ourHolder ;
 Thread ourThread = null;
 boolean isRunning=true;

 public DrawBalloon(Context context) {
 super(context);
 ourHolder= getHolder();
 }

 public DrawBalloon(Context context, AttributeSet attrs) {
        super(context, attrs);
        ourHolder= getHolder();
    }

 public void pause() {
  isRunning=false;
  while(true){
   try{
    ourThread.join();
   } catch (InterruptedException e){
    e.printStackTrace();
   }
   break;
  }
  ourThread=null;
 }

 public void resume(){
  isRunning=true;
  ourThread = new Thread(this);
  ourThread.start();

 }
 @Override
 public void run (){
  while(isRunning){
   if(!ourHolder.getSurface().isValid())
    continue;
            Canvas canvas = ourHolder.lockCanvas();

   updateMic();
   canvas.drawColor(Color.BLACK);
   canvas.drawBitmap(balloon, sensorX, sensorY,null);
   ourHolder.unlockCanvasAndPost(canvas);
  }
 }
}



@Override
protected void onCreate(Bundle savedInstanceState) {
 // TODO Auto-generated method stub
 super.onCreate(savedInstanceState);
 /*sm= (SensorManager) getSystemService(Context.SENSOR_SERVICE);
 if(sm.getSensorList(Sensor.TYPE_ACCELEROMETER).size()!=0){
  Sensor s = sm.getSensorList(Sensor.TYPE_ACCELEROMETER).get(o);
  sm.registerListener(this,s ,SensorManager.SENSOR_DELAY_NORMAL);
 }*/
mic = new Microphone();
balloon = BitmapFactory.decodeResource(getResources(), R.drawable.images);
sensorX=150;
sensorY=350;
//x=y=sensorX=sensorY=0;
//myView= new DrawBalloon (this);
//myView.resume();
//setContentView(R.layout.move_balloon);
setContentView(R.layout.move_balloon);
}



/*@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
 // TODO Auto-generated method stub

}



@Override
public void onSensorChanged(SensorEvent event) {
 // TODO Auto-generated method stub
 try {
  Thread.sleep(20);
 } catch (InterruptedException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
 sensorX=event.values[0];
 sensorY=event.values[1];

}

*/
public void updateMic(){
int level = mic.getLevel();

 sensorY-=level;
}

@Override
public void onBackPressed() {


 finish();


    }


}

这是我的新xml文件：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MoveBalloon"
        android:background="#00000000" >

    <view class="com.example.prova1.MoveBalloon$DrawBalloon" 

        android:id="@+id/drawBalloon1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="182dp" 
        />

</RelativeLayout>

您必须使用类属性

看到这里，我这样做了，但出现了一个错误，并说：元素类型“com.example.prova1.MoveBalloon”后面必须跟属性规范“>”或“/>”。我能做些什么吗？我这样做是为了更改我的xml文件，看起来我已经在上面发布了，但我仍然会遇到以下错误：RuntimeException:无法启动activity ComponentInfo{com.example.prova1/com.example.prova1.MoveBalloon}:android.view.InflateException:二进制XML文件行#8:膨胀类com.example.prova1.MoveBalloon$drableon的错误原因：java.lang.NoSuchMethodException:[类android.content.Context，接口android.util.AttributeSet]使内部类保持静态
