[英]Broadcast Receiver does not deduct calls - Android
我正在嘗試在來電時做一些工作。 我正在嘗試這樣
public class callDeductor extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if(state.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
Toast.makeText(context, "Phone Is Ringing", Toast.LENGTH_LONG).show();
}
if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))
{
Toast.makeText(context, "Call Recieved", Toast.LENGTH_LONG).show();
}
if (state.equals(TelephonyManager.EXTRA_STATE_IDLE))
{
Toast.makeText(context, "Phone Is Idle", Toast.LENGTH_LONG).show();
}
}
}
這是我的宣言:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.deduct.calldeduct"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<application
android:allowBackup="true"
android:icon="@drawable/icon"
android:label="Call Deduct" >
<receiver android:name="com.deduct.calldeduct.callDeductor" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
</application>
</manifest>
我檢查手機和模擬器。 但是它沒有顯示任何吐司消息。 請讓我知道我在哪里做錯了。
繼續與asker對話,作為答案。我剛剛啟動了一個新的Android應用程序,並按照我在評論中所說的進行了工作。.清單如下所示:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dj.randomtest"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="15"
android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<receiver android:name=".CallDetector">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
<activity
android:name=".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>
</application>
CallDetector類看起來像這樣(我們的代碼):
public class CallDetector extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if(state.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
Toast.makeText(context, "Phone Is Ringing", Toast.LENGTH_LONG).show();
}
if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))
{
Toast.makeText(context, "Call Recieved", Toast.LENGTH_LONG).show();
}
if (state.equals(TelephonyManager.EXTRA_STATE_IDLE))
{
Toast.makeText(context, "Phone Is Idle", Toast.LENGTH_LONG).show();
}
}
}
