Android 从未调用onReceive函数

我无法成功注册或使用我的

广播接收器

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

这是我的代码：

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

当我运行活动时，这是日志：

接收更改，一旦创建
接受改变，设定进展
收银员，收银员
接受改变、使用

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

但从未调用onReceive函数

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

谢谢你的帮助：）

我成功了

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

我忘了说：

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

reciverChangeProgress=新的reciverChangeProgress（）

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

我们需要将新对象设置为broadcaseReceiver的新实例

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

reciverChangeProgress=new ReciverChangeProgress();

从不调用onReceive（）

。因为广播从未被发送过。您刚刚注册接收BroadCastReceiver

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

要发送广播，请使用适当的

IntentFilter尝试这些方法

   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}

Intent intent = new Intent("commoshe");
sendBroadcast(intent);

希望它能帮助你
 如果这是真正的代码，那么您可能希望在将“reciverChangeProgress”对象发送到registerReceiver（）方法之前初始化该对象。谢谢。你说得对。现在是工作了。
   public class ReciverChangeProgress extends BroadcastReceiver{

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub
        android.util.Log.e("ReciverChagne", "IReciver");
    }

}

public ReciverChangeProgress reciverChangeProgress;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.e("ReciverChange","onCreate");
    setContentView(R.layout.activity_progress);
    progressBar= (ProgressBar) findViewById(R.id.progressBar1);
    Log.e("ReciverChange","setProgress");
    progressBar.setProgress(UploadService.lastPercent);
    IntentFilter intentFilter=new IntentFilter("commoshe");
    registerReceiver(reciverChangeProgress,intentFilter);
    android.util.Log.e("ReciverChagne", "register");
    sendBroadcast(new Intent("commoshe"));
    android.util.Log.e("ReciverChagne", "Use");

}
