我的应用程序每次在此行崩溃
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));
}
}
}
谢谢。

使用这种方式
runOnUiThread(new Runnable() {
imageView.setImageBitmap(bitmap)
};
答案 1 :(得分：0)
您可以尝试
MainActivity.runOnUithread(new runnable()
{
imageView.setImageBitmap(bitmap);
});
这可能有效
答案 2 :(得分：0)
它正在使用以下代码：
<form action="hello.php" class="js-ajax-php-json" method="post" accept-charset="utf-8">
<input type="text" name="username" value="" placeholder="username" />
<input type="text" name="password" value="" placeholder="password" />
<input type="submit" name="submit" value="Submit form" />
</form>
但是，当我在执行此操作之前，该应用再次崩溃：
$(".js-ajax-php-json").submit(function(){
var data = {
"action": "test"
};
data = $(this).serialize() + "&" + $.param(data);
$.ajax({
type: "POST",
dataType: "json",
url: "hello.php",
data: data,
success: function(data) {
// manipulate response data
// $(".the-return").html(
// "First Value: " + data["username"] + "<br />Second Value: " + data["password"] + "<br />JSON: " + data["json"]
// );
alert("Form submitted successfully.\nReturned json: " + data["json"]);
}
});
return false;
});
这是我遇到的错误（MainActivity.java:111是该行代码）：
runOnUiThread(new Runnable() {
@Override
public void run() {
imageView.setImageBitmap(bitmap);
}
});
