android 5.0 录像模式下只有手动对焦没有自动对焦的问题

1 将FocusManager.java (src\com\android\camera)中的getModeContinousFocusMode函数替换为，

 private String getModeContinousFocusMode(int mode) {

         mode = getSettingModeIndex(mode);

         return MATRIX_FOCUS_MODE_CONTINUOUS[mode];

 }

  

 2 在VideoMode.java(src\com\mediatek\camera\mode)添加：

 1)  在开始部分添加

 import com.mediatek.camera.platform.ICameraDeviceManager.ICameraDevice.AutoFocusMvCallback;

 2)  在文件中合适位置添加一个AutoFocusMvCallback

     protected final AutoFocusMvCallback mAutoFocusMoveCallback = new AutoFocusMvCallback() {

         @Override

         public void onAutoFocusMoving(boolean moving, android.hardware.Camera camera) {

             Log.i(TAG, "[onAutoFocusMoving]moving = " + moving);

             mIFocusManager.onAutoFocusMoving(moving);

         }

     };

 3)  在doStartPreview函数的mICameraDevice.startPreview();后面添加

 mICameraDevice.setAutoFocusMoveCallback(mAutoFocusMoveCallback);

 4)  将cancelAutoFocus函数替换为：

     public void cancelAutoFocus() {

         Log.i(TAG, "[cancelAutoFocus] " + " mICameraDevice = " + mICameraDevice+" mIsAutoFocusCallback = "+mIsAutoFocusCallback);

         if (mICameraDevice != null) {

             mICameraDevice.cancelAutoFocus();

         }

         setFocusState(FOCUS_IDLE);

         setFocusParameters();

         mIsAutoFocusCallback = false;

     }
