我试图在Android中捕获图像,但我收到的错误如下:
致命的例外:主要 处理:com.pace.planes,PID:18741 java.lang.RuntimeException:将结果ResultInfo {who = null,request = 1888,result = -1,data = Intent {dat = content:// media / external / images / media / 4532}}传递给activity {com。 pace.planes / com.pace.planes.Confirmation}:java.lang.NullPointerException
虽然我使用了所有建议的解决方案而不是Stack Overflow。这是我的代码:
captureImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
这里是onActivityResult代码:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode != RESULT_CANCELED && data != null){
if (requestCode == CAMERA_REQUEST && resultCode== Activity.RESULT_OK) {
Bitmap imagebitmap = (Bitmap) data.getExtras().get("data");
Uri tempUri = getImageUri(getApplicationContext(), imagebitmap);
// CALL THIS METHOD TO GET THE ACTUAL PATH
finalFilePath = new File(getRealPathFromURI(tempUri));
// imageBitmap = Compressor.getDefault(this).compressToBitmap(finalFilePath);
captureImage.setScaleType(ImageView.ScaleType.FIT_XY);
imagebitmap = new Compressor.Builder(this)
.setQuality(10)
.setCompressFormat(Bitmap.CompressFormat.PNG)
.setDestinationDirectoryPath(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getAbsolutePath())
.build()
.compressToBitmap(finalFilePath);
captureImage.setImageBitmap(imagebitmap);
//set status image is seleted
IsImageSelected = true;
}
}
}
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
public String getRealPathFromURI(Uri uri) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
