我已经实现了从相机和画廊获取图像的代码,但是在允许访问设备上的照片,媒体和文件权限之后。我检测到了屏幕覆盖。我已关闭所有系统应用程序和其他应用程序的绘制功能,但仍会不断出现。并在恢复和暂停循环上连续运行。 这是我的代码,请帮忙。
这是我的权限代码
if{ (!PermissionsAndroid.getInstance().checkWriteExternalStoragePermission(ServiceDetail_activity.this)) {
PermissionsAndroid.getInstance().requestForWriteExternalStoragePermission((ServiceDetail_activity.this));
} else {
ImageUtils.getInstance().openImageChooser(ServiceDetail_activity.this, ServiceDetail_activity.this);
}
//This is my function to choose the image by camera or gallery
public void openImageChooser(Context context, Activity activity) {
List<Intent> cameraIntents = new ArrayList<>();
Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
PackageManager packageManager = context.getPackageManager();
List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for (ResolveInfo res : listCam) {
String packageName = res.activityInfo.packageName;
Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, setImageUri(context));
cameraIntents.add(intent);
}
Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
galleryIntent.setType("image/*");
Intent chooserIntent = Intent.createChooser(galleryIntent, "Choose");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));
activity.startActivityForResult(chooserIntent, IMAGE_CHOOSER_REQUEST_CODE);
}
这是我的onActivityResult代码
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == Crop.REQUEST_CROP && resultCode == RESULT_OK) {
ImageUtils.getInstance().resampleImage(this, this, ImageUtils.getInstance().getCroppedImagePath(this));
} else if (requestCode == Crop.REQUEST_CROP && resultCode == Crop.RESULT_ERROR) {
// Handle the error got during cropping.
} else if (requestCode == Crop.REQUEST_CROP && resultCode == RESULT_CANCELED) {
// Cropping canceled by user.
}
else if (requestCode == ImageUtils.IMAGE_CHOOSER_REQUEST_CODE &&resultCode== Activity.RESULT_OK) {
final boolean isCamera;
if (data == null || data.getData() == null) {
isCamera = true;
} else {
final String action = data.getAction();
if (action == null) {
isCamera = false;
} else {
isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
}
}
if (isCamera) {
selectedImagePath = ImageUtils.getInstance().getImagePath(this);
} else {
selectedImagePath = FileUtils.getPath(this, data.getData());
}
if ((selectedImagePath != null) && !(selectedImagePath.equals(""))) {
ImageUtils.getInstance().beginCrop(this, this, selectedImagePath, false);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
// super.onRequestPermissionsResult(requestCode, permissions, grantResults);
ActivityCompat.requestPermissions(this, permissions, requestCode);
}
This my manifest code.
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
我在搜索上做了很多事情,但是不明白。
请向我推荐我错了的地方。我整日迷失了。
我已经在棉花糖设备6.0中对此进行了测试。如果有任何好友建议给我,请找出这个问题。这是我项目中非常重要的部分。感谢提前。
