6572KK下栏状态栏增加来电闪烁开关

来源：互联网发布：excel数据比对怎么做编辑：程序博客网时间：2024/05/22 12:44

打开开关监听来电，来电时控制闪光灯闪烁

1、SystemUI/ext/src/com/mediatek/systemui/ext/QuickSettingsTileViewId.java

增加ID :

在 QuickSettingsTileViewId 方法中加上此开关的ID: ID_INCALL_FLASHING_LED,

2、SystemUI/src/com/android/systemui/statusbar/phone/QuickSettings.java

确认开关的位置

在 addSystemTiles 方法中加上要加入的代码

private void addSystemTiles(ViewGroup parent, LayoutInflater inflater) {

                   ...
           addInCallFlashingLedTile(parent, inflater);
       }

addInCallFlashingLedTile的具体实现

    private void addInCallFlashingLedTile(ViewGroup parent, LayoutInflater inflater) {
        final QuickSettingsBasicTile inCallFlashLed = new QuickSettingsBasicTile(mContext);
        boolean enabled = Settings.System.getInt(mContext.getContentResolver(), "incall_flashing_led", 0) != 0; //开关默认关闭
        if (enabled) {
           inCallFlashLed.setImageResource(R.drawable.ic_incall_flashing_led_enabled);
       } else {
           inCallFlashLed.setImageResource(R.drawable.ic_incall_flashing_led_disenabled);
       }
        inCallFlashLed.setTextResource(R.string.quick_settings_incall_flashing_led);
        inCallFlashLed.setTileViewId(QuickSettingsTileViewId.ID_INCALL_FLASHING_LED);
        inCallFlashLed.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               boolean enabled = Settings.System.getInt(mContext.getContentResolver(), "incall_flashing_led", 0) != 0;
               if (enabled) {
                   Settings.System.putInt(mContext.getContentResolver(), "incall_flashing_led", 0);
                   inCallFlashLed.setImageResource(R.drawable.ic_incall_flashing_led_disenabled);
               } else {
                   Settings.System.putInt(mContext.getContentResolver(), "incall_flashing_led", 1);
                   inCallFlashLed.setImageResource(R.drawable.ic_incall_flashing_led_enabled);
               }
            }
        });
        parent.addView(inCallFlashLed);
    }

图片和字符串资源需添加

3、SystemUI/src/com/android/systemui/SystemUIService.java

监听来电及打开摄像头闪光灯的关键代码

添加代码：

    private static final long OPEN_DELAYED_TIME = 300; // 闪烁频率
    private static final long CLOSE_DELAYED_TIME = 500;//间隔

    private TelephonyManager mTelephonyManager;
    private Camera mCamera;
    private Parameters mParameter;
    private Handler mFlashHandler;

    private boolean mIsInCall = false;
    private boolean mIsOpen = false;

    private void initInCallFlashLed() {
       mIsInCall = false;
       mIsOpen = false;
       if (true) {
           mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
           mTelephonyManager.listen(MyPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
           mFlashHandler = new Handler();
       }
   }

   private void releaseInCallFlashLed() {
       if (mCamera != null) {
           mCamera.stopPreview();
           mCamera.release();
           mParameter = null;
           mCamera = null;
       }
       mFlashHandler.removeCallbacks(mFlashRunnable);
       mTelephonyManager = null;
       mFlashHandler = null;
   }

   @Override
   public void onDestroy() {
       super.onDestroy();
       releaseInCallFlashLed();
   }

    private PhoneStateListener MyPhoneStateListener = new PhoneStateListener() {
       @Override
       public void onCallStateChanged(int state, String incomingNumber) {
           super.onCallStateChanged(state, incomingNumber);
           switch (state) {
           case TelephonyManager.CALL_STATE_IDLE:
               mIsInCall = false;
               closeFlashLight();
               break;
           case TelephonyManager.CALL_STATE_RINGING:
               mIsInCall = true;
               openFlashLight();
               break;
           case TelephonyManager.CALL_STATE_OFFHOOK:
               closeFlashLight();
               break;
           }
       }
   };

   private void openFlashLight() {
       if (mIsInCall) {
           try {
               if(mCamera == null){
                   mCamera = Camera.open();
               }
               mCamera.startPreview();
               mParameter = mCamera.getParameters();
               boolean enabled = Settings.System.getInt(getContentResolver(), "incall_flashing_led", 0) != 0;
               if (enabled) {
                   mFlashHandler.post(mFlashRunnable);
               }
           } catch (java.lang.RuntimeException e) {
               Log.d(TAG, "openFlashLight=>error: " + e.toString());
           }
       }
   }

   private void closeFlashLight() {
       if (mCamera != null) {
           mCamera.stopPreview();
           mCamera.release();
           mParameter = null;
           mCamera = null;
       }
       mFlashHandler.removeCallbacks(mFlashRunnable);
   }

   private Runnable mFlashRunnable = new Runnable() {
       @Override
       public void run() {
           if (mIsOpen) {
               mIsOpen = false;
               if (mCamera != null && mParameter != null) {
                   mParameter.setFlashMode(Parameters.FLASH_MODE_OFF);
                   mCamera.setParameters(mParameter);
                   mFlashHandler.postDelayed(mFlashRunnable, OPEN_DELAYED_TIME);
               }
           } else {
               mIsOpen = true;
               if (mCamera != null && mParameter != null) {
                   mParameter.setFlashMode(Parameters.FLASH_MODE_TORCH);
                   mCamera.setParameters(mParameter);
                   mFlashHandler.postDelayed(mFlashRunnable, CLOSE_DELAYED_TIME);
               }
           }
       }
   };

导入包：

import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.os.Handler;
import android.hardware.Camera;
import android.hardware.Camera.Parameters;
import android.content.Context;
import android.provider.Settings;

最后在onCreate()方法中加上 initInCallFlashLed();

public void onCreate() {

...

initInCallFlashLed();

}

注意在AndroidManifest.xml中加入权限：

<uses-permission android:name="android.permission.FLASHLIGHT" />
<uses-permission android:name="android.permission.CAMERA"/>
