【中文标题】如何解决：二进制 XML 文件第 8 行：膨胀类时出错 [重复]

【英文标题】：How to solve : Binary XML file line #8: Error inflating class [duplicate]

【问题描述】：

我的应用包括在用户说话时移动图片。我已经这样做了，但是当我尝试将图像设置为我的应用程序的背景时遇到了问题。我正在尝试使用 xml 文件执行此操作，但我得到了 Error inflating 类。任何人都可以帮助我吗？ 提前致谢

xml类中的第8行是：

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

logcat 说：

我试图与 xml 连接的 MoveBallon 类是这样的

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_
    android:layout_
    tools:context=".MoveBalloon"
        android:background="#00000000" >

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

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

</RelativeLayout>

【参考方案1】：

你必须使用类属性

看到这个Error referencing an inner class View in layout/main.xml

【讨论】：

我做了这个但是发生了一个错误并说：元素类型“com.example.prova1.MoveBalloon”必须后跟属性规范，“>”或“/>”。

有什么我可以做的吗？

我做了这个，所以我更改了我的 xml 文件，看起来我已经在上面发布了，但我仍然收到此错误：RuntimeException: Unable to start activity ComponentInfocom.example.prova1/com. example.prova1.MoveBalloon: android.view.InflateException: Binary XML file line #8: Error inflating class com.example.prova1.MoveBalloon$DrawBalloon 原因：java.lang.NoSuchMethodException: [class android.content.上下文、接口android.util.AttributeSet]

让你的内部类静态
