我有一个应用程序，可以从我的应用程序中拍照。

它在 Motorola RAZR HD Android 4.1.2 和 Galaxy S3 Android 4.1.1 上运行良好。

这两款手机之间的唯一区别是，当我使用摩托罗拉 RAZR 的应用程序拍照时，我可以预览图像，而当我使用三星 Galaxy S3 时，这不起作用。

我也想在三星中预览图像。我怎么能这样做？

此代码在我的主要活动中

setContentView(R.layout.principal_activity);
principalActivity_bt_TirarFoto = (Button) findViewById(R.id.principalActivity_bt_TirarFoto);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
cameraSurfaceView = new CameraSurfaceView(principalActivity_bt_TirarFoto.getContext());
cameraSurfaceView.setSoundEffectsEnabled(true);
cameraSurfaceView.setDrawingCacheEnabled(true);
preview = (FrameLayout) findViewById(R.id.principalActivity_fl_Camera);

preview.addView(cameraSurfaceView);

principalActivity_bt_TirarFoto.setSoundEffectsEnabled(true);
principalActivity_bt_TirarFoto.setOnClickListener(new OnClickListener() {

@SuppressLint("NewApi") 
@Override
public void onClick(View v) {
    Log.i("PrincipalActivity","onClick - TirarFoto");
camera = cameraSurfaceView.getCamera();
camera.takePicture(new ShutterCallback() {

@Override
    public void onShutter() {
        AudioManager mgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
        mgr.playSoundEffect(AudioManager.FLAG_PLAY_SOUND);

                }
            }, null, hps = new HandlePictureStorage());

            imageSelected = false;

            mostrarBotoesConfirma();

        }
    });

这是我的 PictureCallback

public class HandlePictureStorage implements PictureCallback {

int wid = 0;
Bitmap newImage;

public HandlePictureStorage(){
}

@Override
public void onPictureTaken(byte[] picture, Camera camera) {

    Matrix matrix = new Matrix();

    Bitmap cameraBitmap = BitmapFactory.decodeByteArray(picture, 0, picture.length);

    wid = 612;

    Bitmap scaledBitmap = Bitmap.createScaledBitmap(cameraBitmap, wid, wid, true);
    Bitmap imagemRotacionada = Bitmap.createBitmap(scaledBitmap,0,0,scaledBitmap.getWidth(),scaledBitmap.getHeight(),matrix,true);

    newImage = Bitmap.createBitmap (612, 612, Bitmap.Config.ARGB_8888);

    Canvas canvas = new Canvas(newImage);
    canvas.drawBitmap(imagemRotacionada, 0f, 0f, null);

    cameraBitmap.recycle();
    cameraBitmap = null;
}

public Bitmap getBitmap(){
    return newImage;
}

}

谢谢！

这是 logcat @Segi。我运行我的应用程序并拍照，这是他提供的日志。

好的。

我找到了解决方案。

就像@Segi 之前说的。S3 有一个错误，为了避免这种情况我做了。

首先我得到手机的型号

String phoneModel = android.os.Build.MODEL;

然后我验证什么时候给模型拍照。如果它是 Galaxy S3，我会使用我的 cameraSurfaceView 的 setBackground 方法。这是代码。

if (phoneModel.equals("GT-I9305T")){
   camera.takePicture(new ShutterCallback() {

   @Override
   public void onShutter() {
       AudioManager mgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
       mgr.playSoundEffect(AudioManager.FLAG_PLAY_SOUND);
   }
}, null, new Camera.PictureCallback(){

    @Override
    public void onPictureTaken(byte[] data, Camera camera) {

    int wid = 0;

    Matrix matrix = new Matrix();
    matrix.setRotate(90);

    Bitmap cameraBitmap = BitmapFactory.decodeByteArray(data, 0, data.length);

    wid = 612;

    Bitmap scaledBitmap = Bitmap.createScaledBitmap(cameraBitmap, wid, wid, true);
    Bitmap imagemRotacionada = Bitmap.createBitmap(scaledBitmap,0,0,scaledBitmap.getWidth(),scaledBitmap.getHeight(),matrix,true);

    imagemS3 = Bitmap.createBitmap (612, 612, Bitmap.Config.ARGB_8888);

    Canvas canvas = new Canvas(imagemS3);
    canvas.drawBitmap(imagemRotacionada, 0f, 0f, null);

    cameraBitmap.recycle();
    cameraBitmap = null;

    scaledBitmap.recycle();

    imagemRotacionada.recycle();

    Drawable imageDrawable = new BitmapDrawable(getResources(),imagemS3);
    cameraSurfaceView.setBackground(imageDrawable);

}});

或者你可以在这里查看我在哪里找到了解决方案。

S3(GT-I9300) 相机预览架错误
