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;

    }
