Question

我正在倾听连接和断开我银河系的力量。

我创建了2个BroadCastReceivers，一个用于连接，另一个用于断开连接。

当我尝试实施时，即使断开电源线，我也只能获得连接的数据。

意图被发送，但看起来是错误的。

以下是活动代码：

        //      Handle Power On
    PowerConnectedBCReceiver myPowerConnectedBCReceiver = new PowerConnectedBCReceiver();
    IntentFilter intentPowerOnFilter = new IntentFilter();
    intentPowerOnFilter.addAction("android.intent.action.ACTION_POWER_CONNECTED");
    registerReceiver(myPowerConnectedBCReceiver, intentPowerOnFilter);

    BroadcastReceiver PowerConnectedReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            showToast("connected");
        }
    };



    //      Handle Power Off
    PowerConnectedBCReceiver myPowerDisonnectedBCReceiver = new PowerConnectedBCReceiver();
    IntentFilter intentPowerDisconnectedOnFilter = new IntentFilter();
    intentPowerDisconnectedOnFilter.addAction("android.intent.action.ACTION_POWER_DISCONNECTED");
    registerReceiver(myPowerDisonnectedBCReceiver, intentPowerDisconnectedOnFilter);

    BroadcastReceiver PowerDisconnectedReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            showToast("disconnected");
        }
    };

注册BC以完成工作

        registerReceiver(PowerDisconnectedReceiver, new IntentFilter("com.neglected.POWER_DISCONNECTED"));
    registerReceiver(PowerConnectedReceiver, new IntentFilter("com.neglected.POWER_CONNECTED"));

BroadCast连接代码：

public class PowerConnectedBCReceiver extends BroadcastReceiver
{ 
@Override
public void onReceive(Context context, Intent intent) 
{
    Toast.makeText(context,  "Phone was connected to power" , Toast.LENGTH_LONG).show();
    Intent tIntent = new Intent("com.neglected.POWER_CONNECTED");
    context.sendBroadcast(tIntent);
}

}

广播断开代码：

public class PowerDisconnectedBCReceiver extends BroadcastReceiver
{ 
@Override
public void onReceive(Context context, Intent intent) 
{

    Toast.makeText(context,  "Phone was disconnected from power" , Toast.LENGTH_LONG).show();
    Intent tIntent = new Intent("com.neglected.POWER_DISCONNECTED");
    context.sendBroadcast(tIntent);
}

}

代码错了吗？我可以听这两个动作吗？ seperately？我看不到额外发送了CONNNECTED动作，是吗？

Answer 1

不确定你的最后两个班级（* BCReeivers）应该做什么。你的第一段代码看起来不错。如果重要的话，它将限于封闭活动的生命周期。

对于Galaxy S，您可能无法依赖这些意图。特别是，我发现Verizon Fascinate（他们的Galaxy S版本）非常大。见这里：http://devblog.bu.mp/how-to-ddos-yourself

Answer 2

我的广播实例中出错。我错误地使用 PowerConnectedBCReceiver 而不是 PowerDisconnectedBCReceiver

问题解决了。
