在Android中定制呼入/呼出电话屏幕

Question

我正在尝试实现自定义的呼入/呼出屏幕。以下是我尝试的内容，遇到了两个问题：

1. 有时它会调用我手机上的默认呼入屏幕，有时它会调用自定义屏幕。我希望手机总是调用自定义屏幕。

2. 我无法发起呼叫。自定义屏幕弹出来，但不会拨打任何电话。

我不确定如何解决这个问题。如果有人能帮我解决这个问题，那就太好了。

以下是我正在尝试的内容：

清单：

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar" >
    <activity
        android:name="com.honey.ringer.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.honey.ringer.AcceptCall"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" >
        <intent-filter>
            <action android:name="android.intent.action.ANSWER" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

    <receiver
        android:name="com.honey.ringer.PhoneListenerBroad">
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>
</application>

BroadcastReceiver：这个类既可以接收广播也可以发送广播。

public class PhoneListenerBroad extends BroadcastReceiver
{

Context c;
private String outgoing;

@Override
public void onReceive(Context context, Intent intent) 
{
    c = context;

    if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) 
    {
        outgoing = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); 
        int state = 2;
        Intent intentPhoneCall = new Intent(c, AcceptCall.class);
        intentPhoneCall.putExtra("incomingnumber", outgoing);
        intentPhoneCall.putExtra("state", state);
        intentPhoneCall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        c.startActivity(intentPhoneCall);
    }

    try
    {
        TelephonyManager tmgr = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        MyPhoneStateListener PhoneListener = new MyPhoneStateListener();
        tmgr.listen(PhoneListener, PhoneStateListener.LISTEN_CALL_STATE);
    }
    catch (Exception e) 
    {
        Log.e("Phone Receive Error", " " + e);
    }

}

private class MyPhoneStateListener extends PhoneStateListener
{
    public void onCallStateChanged(final int state, final String incomingNumber) 
    {
        Handler callActionHandler = new Handler();
        Runnable runRingingActivity = new Runnable() 
        {
            @Override
            public void run() 
            {
                if (state == 1)
                {
                    Intent intentPhoneCall = new Intent(c, AcceptCall.class);
                    intentPhoneCall.putExtra("incomingnumber", incomingNumber);
                    intentPhoneCall.putExtra("state", state);
                    intentPhoneCall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    c.startActivity(intentPhoneCall);
                }
            }
        };

        if (state == 1)
        {   
            callActionHandler.postDelayed(runRingingActivity, 100);
        }

        if (state == 0) 
        {
            callActionHandler.removeCallbacks(runRingingActivity);
        }
    }
}

}

你找到解决办法了吗？我也有类似的问题。 - Basher51

@Basher51 - 你遇到的问题是接收方面还是发送方面？ - TheDevMan

我的问题是一个外向性问题。我正在创建一个亭子应用程序，用户可以使用它进行电话呼叫。为此，我想创建一个定制的呼出屏幕，以替换默认的呼出屏幕。 - Basher51

Answer 1

对于呼出电话：作为一种解决方法，我做了以下操作，现在运行良好。我创建了一个具有清单中所需的所有权限的呼出接收器。

通过使用处理程序延迟调用活动。

像这样：

@Override
public void onReceive(Context context, Intent intent) 
{
    c = context;
    setResultData(null);
    phonenumber = getResultData();
    if (phonenumber == null)
    {
        phonenumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
    }
    setResultData(phonenumber);
    callActionHandler.postDelayed(runRingingActivity, 1000);
}


Handler callActionHandler = new Handler();
Runnable runRingingActivity = new Runnable() 
{
    @Override
    public void run() 
    {

        Intent intentPhoneCall = new Intent(c, OutgoingCallActivity.class);
        intentPhoneCall.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intentPhoneCall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        c.startActivity(intentPhoneCall);
    }
};

您可以使用电话号码将其发送到新活动。

如果您有任何问题，请告诉我！

这里是否有事件可以知道呼出电话是否结束/被接听？ - ralphgabb
