我正在尝试在Google Glass中显示实时相机预览.

我正在使用所有相机默认设置(并且还尝试使用一些不同的图像格式;理想情况下,我可以使用其中一种YUV格式),但显示屏中显示的图像是乱码,如下所示:

布局很简单:

<?xml version="1.0" encoding="utf-8"?>
<TextureView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/scan_preview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

这是活动代码:

public class ScanActivity extends Activity {
    private static final String kTag = ScanActivity.class.getSimpleName();
    private TextureView mVideoCaptureView = null;
    private Camera mCamera = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_scan);
        setTitle(R.string.title_scan);

        mVideoCaptureView = (TextureView) findViewById(R.id.scan_preview);
        mVideoCaptureView.setKeepScreenOn(true);
        mVideoCaptureView.setSurfaceTextureListener(new VideoCaptureTextureListener());
    }

    @Override
    protected void onPause() {
        super.onPause();
        stopVideo();
    }

    @Override
    protected void onResume() {
        super.onResume();
        startVideo();
    }

    private void startVideo() {
        if (mCamera != null) {
            mCamera.release(); …

我试图在谷歌玻璃上使用zxing,但是我收到了上面的错误.

我使用zxing 2.2 core.jar我也在设备显示屏上收到此错误消息"抱歉,安卓摄像头遇到问题.您可能需要重启设备".

我正在对我的oncreate活动发起意图

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 0);
}

Eclipse错误消息
