尝试显示位图时应用程序崩溃

Question

我的应用程序每次都在这一行崩溃

imageView.setImageBitmap(bitmap);

我绝对确定它来自那条线。这是我得到的错误：

这是我的代码：

public class MainActivity extends AppCompatActivity {

    private CameraView cameraView;
    private FocusView focusView;
    private ImageView imageView;

    private Fotoapparat fotoapparat;

    private static final String TAG = MainActivity.class.getSimpleName();


    private Fotoapparat createFotoapparat() {
        return Fotoapparat
                .with(this)
                .into(cameraView)
                .focusView(focusView)
                .previewScaleType(ScaleType.CenterCrop)
                .lensPosition(back())
                .frameProcessor(new SampleFrameProcessor())
                .logger(loggers(
                        logcat(),
                        fileLogger(this)
                ))
                .cameraErrorCallback(new CameraErrorListener() {
                    @Override
                    public void onError(@NotNull CameraException e) {
                        Toast.makeText(MainActivity.this, e.toString(), Toast.LENGTH_LONG).show();
                    }
                })
                .build();
    }


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        cameraView = findViewById(R.id.cameraView);
        focusView = findViewById(R.id.focusView);
        imageView = findViewById(R.id.imageView);

        fotoapparat = createFotoapparat();
    }

    @Override
    protected void onStart() {
        super.onStart();
        fotoapparat.start();
    }

    @Override
    protected void onStop() {
        super.onStop();
        fotoapparat.stop();
    }

    private class SampleFrameProcessor implements FrameProcessor {
        @Override
        public void process(@NotNull Frame frame) {
            // Perform frame processing, if needed
            byte nv21bytearray[] = frame.getImage();
            Resolution size = frame.getSize();
            Integer height = size.height;
            Integer width = size.width;
            //Log.i(TAG, height.toString());

            YuvImage yuvImage = new YuvImage(nv21bytearray, ImageFormat.NV21, width, height, null);
            ByteArrayOutputStream os = new ByteArrayOutputStream();
            yuvImage.compressToJpeg(new Rect(0, 0, width, height), 100, os);
            byte[] jpegByteArray = os.toByteArray();
            Bitmap bitmap = BitmapFactory.decodeByteArray(jpegByteArray, 0, jpegByteArray.length);
            //imageView.setImageBitmap(Bitmap.createScaledBitmap(bitmap, 512, 512, false));
            imageView.setImageBitmap(bitmap);
            //Log.i(TAG, getString(bitmap.getHeight()));
            //int size1 = bitmap.getPixel(20,20);
            //int rood = red(size1);
            //Log.i(TAG, String.valueOf(rood));

        }
    }
}

提前致谢。

Answer 1

use this way

runOnUiThread(new Runnable() { 
imageView.setImageBitmap(bitmap)
 };

Answer 2

你可以试试这个

MainActivity.runOnUithread(new runnable()
{
imageView.setImageBitmap(bitmap);
});

这可能有用

Answer 3

正在使用此代码：

runOnUiThread(new Runnable() {
            @Override
            public void run() {
                imageView.setImageBitmap(bitmap);
            }
        });

但是，当我之前这样做时，应用程序再次崩溃：

bitmap.setPixel(20, 20, Color.WHITE);

这是我遇到的错误（MainActivity.java:111 是那行代码）：
