Question

当电话状态响起时，我想运行一个活动来显示我自己的屏幕。

我正在使用：

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);

和

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

但是当显示活动时，通知栏不会隐藏。

浏览以下代码段：

创建BroadCastReceiver类以侦听来电最高优先级：

<强> Manifest.xml ：

<receiver android:name=".MyPhoneBroadcastReceiver">
    <intent-filter android:priority="99999">
        <action android:name="android.intent.action.PHONE_STATE" />
    </intent-filter>
</receiver>

然后在课堂上，onReceive()方法打开CustomCallsReceiver活动，其意图操作为 "android.intent.action.ANSWER"

@Override
public void onReceive(final Context context, Intent intent) {

Bundle extras = intent.getExtras();

if (extras != null) {

    String state = extras.getString(TelephonyManager.EXTRA_STATE);          
    final String incomingNumber = extras.getString("incoming_number");

    Handler callActionHandler = new Handler();

    Runnable runRingingActivity = new Runnable(){
        @Override
        public void run() {
             //Notice the intent, cos u will add intent filter for your class(CustomCallsReceiver)
            Intent intentPhoneCall = new Intent("android.intent.action.ANSWER");
            intentPhoneCall.putExtra("INCOMING_NUM", incomingNumber);
            intentPhoneCall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(intentPhoneCall);
        }
    };
    if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
        //increase the delay amount if problem occur something like -the screen didn't show up- that's the key about this method(the delay).
        callActionHandler.postDelayed(runRingingActivity, 100);    
    }
    if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
        callActionHandler.removeCallbacks(runRingingActivity);
    }

}
}

将此意图过滤器添加到manifest file以用于您将要学习的课程用作自定义呼叫接收器。

    <activity android:name="CustomCallsReceiver" android:noHistory="true" android:screenOrientation="portrait" >
    <intent-filter>
        <action android:name="android.intent.action.ANSWER" />
         <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>    
</activity>

CustomeCallsReceiver班级：

public class CustomCallsReceiver extends Activity {

 private String TAG = "CustomCallsReceiver";
 String incomingNumber, caller;

 @Override
   public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.custome_calls_receiver);

TextView number = (TextView) findViewById(R.id.number);
number.setGravity(Gravity.CENTER);

incomingNumber = getIntent().getExtras().getString("INCOMING_NUM");
caller = getCallerName(incomingNumber);

if (caller != null) {
    number.setText(caller + "\n" + incomingNumber);  }  
        }

最后当然不要忘记添加主题不是标题或 manifest文件

上的通知栏

 <application
      android:theme="@android:style/Theme.NoTitleBar.Fullscreen">

希望这对你有用......

在android中传入呼叫时隐藏通知栏
