如何在Android中自定义相机布局（） _如何在

赋料扬雄敌，诗看子建亲。这篇文章主要讲述如何在Android中自定义相机布局？相关的知识，希望能为你提供帮助。
我正在尝试使用文本识别功能开发某种OCR应用程序。我写了并找到了一些正常工作的代码，但我的问题是我想在相机布局中进行一些自定义。我想添加自己的捕获按钮并添加一个框架。我实际上是在“表面视图/持有者”的不同项目中完成的。但我无法实现我的项目，因为它的工作方式不同。

public class MainActivity extends AppCompatActivity {private static final int REQUEST_GALLERY = 0; private static final int REQUEST_CAMERA = 1; private static final String TAG = MainActivity.class.getSimpleName(); private Uri imageUri; private TextView detectedTextView; // layouttaki text view@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); findViewById(R.id.choose_from_gallery).setOnClickListener(new View.OnClickListener() {// galeriden resim se?me i?lemi @Override public void onClick(View v) { Intent intent = new Intent(); intent.setType("image/*"); intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(intent, REQUEST_GALLERY); } }); findViewById(R.id.take_a_photo).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) {// resim ?ekme i?lemiString filename = System.currentTimeMillis() + ".jpg"; ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, filename); values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg"); imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); Intent intent = new Intent(); intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); startActivityForResult(intent, REQUEST_CAMERA); } }); detectedTextView = (TextView) findViewById(R.id.detected_text); detectedTextView.setMovementMethod(new ScrollingMovementMethod()); }private void inspectFromBitmap(Bitmap bitmap) {//kendisine gelen bitmap resimden inspect yaparTextRecognizer textRecognizer = new TextRecognizer.Builder(this).build(); try { if (!textRecognizer.isOperational()) { new AlertDialog. Builder(this). setMessage("Text recognizer could not be set up on your device").show(); return; }Frame frame = new Frame.Builder().setBitmap(bitmap).build(); SparseArray< TextBlock> origTextBlocks = textRecognizer.detect(frame); List< TextBlock> textBlocks = new ArrayList< > (); for (int i = 0; i < origTextBlocks.size(); i++) { TextBlock textBlock = origTextBlocks.valueAt(i); textBlocks.add(textBlock); } Collections.sort(textBlocks, new Comparator< TextBlock> () { @Override public int compare(TextBlock o1, TextBlock o2) { int diffOfTops = o1.getBoundingBox().top - o2.getBoundingBox().top; int diffOfLefts = o1.getBoundingBox().left - o2.getBoundingBox().left; if (diffOfTops != 0) { return diffOfTops; } return diffOfLefts; } }); StringBuilder detectedText = new StringBuilder(); for (TextBlock textBlock : textBlocks) { if (textBlock != null & & textBlock.getValue() != null) { detectedText.append(textBlock.getValue()); detectedText.append(" "); } }detectedTextView.setText(detectedText); // detectedText is a final string } finally { textRecognizer.release(); } }private void inspect(Uri uri) { InputStream is = null; Bitmap bitmap = null; try { is = getContentResolver().openInputStream(uri); BitmapFactory.Options options = new BitmapFactory.Options(); options.inPreferredConfig = Bitmap.Config.ARGB_8888; options.inSampleSize = 2; options.inScreenDensity = DisplayMetrics.DENSITY_LOW; bitmap = BitmapFactory.decodeStream(is, null, options); Bitmap rotatedMap = RotateBitmap(bitmap,90); inspectFromBitmap(rotatedMap); } catch (FileNotFoundException e) { Log.w(TAG, "Failed to find the file: " + uri, e); } finally { if (bitmap != null) { bitmap.recycle(); } if (is != null) { try { is.close(); } catch (IOException e) { Log.w(TAG, "Failed to close InputStream", e); } } } }@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode) { case REQUEST_GALLERY: if (resultCode == RESULT_OK) { inspect(data.getData()); } break; case REQUEST_CAMERA: if (resultCode == RESULT_OK) { if (imageUri != null) { inspect(imageUri); } } break; default: super.onActivityResult(requestCode, resultCode, data); break; } }public static Bitmap RotateBitmap(Bitmap source, float angle) // it rotates the bitmap for given parameter { Matrix matrix = new Matrix(); matrix.postRotate(angle); return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(), matrix, true); }

【如何在Android中自定义相机布局（）】在那种情况下，我该怎么办？感谢你们。
答案不，您无法更改满足ACTION_IMAGE_CAPTURE意图的相机应用程序的布局。实际上，不同的设备不会有相同的相机应用程序。每个人可能会有非常不同的外观。您需要一个“自定义摄像头”来控制其布局和UX。
