通话保持常亮
在网上搜索的 Android保持屏幕常亮的方法，一种是 getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
另一种是通过 wakeLock, 经过测试发现在 InCallActivity.java 中 onCreate()使用第一种并不生效，看网上说的要放到 setContentView()之前
然而试了也没生效，放到自己写的测试demo中，继承自 AppCompatActivity， setFlags需要传递两个参数，如下的方法生效了
getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
修改 InCallActivity 中的方法，编译时发现报错了，参数不合法，看到 InCallActivity 继承自 FragmentActivity， 不知道跟这个有没有关系，
于是采用第二种方法。
修改位置
alps\vendor\mediatek\proprietary\packages\apps\Dialer\java\com\android\incallui\InCallActivity.java
private PowerManager.WakeLock mWakeLock;
@Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
//getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
//add keep inCallActivity keepScreenOn
PowerManager powerManager= (PowerManager) getSystemService(Context.POWER_SERVICE);
mWakeLock = powerManager.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "keep_screen_on_tag");
}
@Override
protected void onResume() {
super.onResume();
mWakeLock.acquire();
}
@Override
protected void onDestroy() {
super.onDestroy();
mWakeLock.release();
}
android.permission.WAKE_LOCK 权限 AndroidManifest 文件中已经存在，就不用添加了
接听方式上下滑动，改为按钮接听
安卓源码中提供了两种接听方式，一种为上下滑动，另一种为按钮接听。有点像苹果手机接听一样，有时候是滑动接听，
有时候是两个按钮，一个绿色的接听，一个红色的挂断。效果图如下
滑动接听方式
按钮接听方式
修改位置
vendor\mediatek\proprietary\packages\apps\Dialer\java\com\android\incallui\answer\impl\answermethod\AnswerMethodFactory.java
@NonNull
public static AnswerMethod createAnswerMethod(@NonNull Activity activity) {
if (needTwoButton(activity)) {
return new TwoButtonMethod();
} else {
//return new FlingUpDownMethod();
return new TwoButtonMethod();
}
}
TwoButtonMethod.java 对应按钮接听方式
FlingUpDownMethod.java 对应滑动接听方式
简单说下逻辑，接听界面对应的类为 AnswerFragment，布局文件为 fragment_incoming_call，
接听部分布局id为 answer_method_container，通过加载 Fragment 进行替换
AnswerMethodFactory.createAnswerMethod(getActivity())，此方法去实例化按钮接听方式和滑动接听方式
接通时发送广播通知app(通话界面开始计时)
为啥需要这么干，通过监听状态改变也能判断电话接通，但是没有系统优先级高，这就需要我们来改源码了
**8.1 修改位置 **
vendor\mediatek\proprietary\packages\apps\Dialer\java\com\android\incallui\contactgrid\ContactGridManager.java
public void setCallState(PrimaryCallState primaryCallState) {
this.primaryCallState = primaryCallState;
if (DialerCall.State.ACTIVE == primaryCallState.state) {
Log.e("InCallFragment", "sendBrocast Call.State.ACTIVE =" + primaryCallState.state);
//cczheng add , send broadcast when is active
Intent broIntent = new Intent();
broIntent.setAction("com.call.state.active");
context.sendBroadcast(broIntent);
//cczheng add , send broadcast when is active
}
updatePrimaryNameAndPhoto();
updateBottomRow();
updateTopRow();
}
6.0 修改位置
packages\apps\InCallUI\src\com\android\incallui\CallCardFragment.java
@Override
public void setCallState(
int state,
int videoState,
int sessionModificationState,
DisconnectCause disconnectCause,
String connectionLabel,
Drawable callStateIcon,
String gatewayNumber,
boolean isWifi,
boolean isConference) {
boolean isGatewayCall = !TextUtils.isEmpty(gatewayNumber);
CallStateLabel callStateLabel = getCallStateLabelFromState(state, videoState,
sessionModificationState, disconnectCause, connectionLabel, isGatewayCall, isWifi,
isConference);
....
if (Call.State.ACTIVE == state) {
Log.d(this, "sendBrocast Call.State.ACTIVE " + state);
//cczheng add , send broadcast when is active
Intent broIntent=new Intent();
broIntent.setAction("com.call.state.active");
getActivity().sendBroadcast(broIntent);
if(CallUtils.isVideoCall(videoState)){
//videoCall
final View buttonsView=getView().findViewById(R.id.buttons_container);
buttonsView.setBackgroundColor(Color.argb(0x99,0xff,0xff,0xff));
videoFragment.setBGColor(Color.argb(0xff,0x00,0x00,0x00));
}
}
}
简单说下，通过打印日志可以看到8.1的接通状态值变化为
