如何在Android 5.0（Lollipop）中以編程方式回復(fù)來電？當(dāng)我嘗試為來電創(chuàng)建自定義屏幕時，我正在嘗試以編程方式接聽來電。我使用以下代碼但它在Android 5.0中不起作用。// Simulate a press of the headset button to pick up the callIntent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON); buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));context.sendOrderedBroadcast(buttonDown, "android.permission.CALL_PRIVILEGED");// froyo and beyond trigger on buttonUp instead of buttonDownIntent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON); buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));context.sendOrderedBroadcast(buttonUp, "android.permission.CALL_PRIVILEGED");

完全可行的解決方案基于@Valter Strods代碼。
要使其正常工作，您必須在鎖定屏幕上顯示（不可見）活動，其中執(zhí)行代碼。
AndroidManifest.xml中
<uses-permission android:name="android.permission.WAKE_LOCK" /><uses-permission android:name="android.permission.DISABLE_KEYGUARD" /><activity android:name="com.mysms.android.lib.activity.AcceptCallActivity" android:launchMode="singleTop" android:excludeFromRecents="true" android:taskAffinity="" android:configChanges="orientation|keyboardHidden|screenSize" android:theme="@style/Mysms.Invisible"> </activity>
