我尝试创建一个应用程序,可以从相机捕获图像并根据图像路径显示结果。内,其处理捕获图像,如下捕获图像后的更新库android
btnImg.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
try {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
file = new File(Environment.getExternalStorageDirectory() + File.separator + "Nama_foto_" + waktu + ".jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
intent.putExtra("return-data", true);
getParentFragment().startActivityForResult(intent, CAPTURE_IMAGE);
}catch (ActivityNotFoundException anfe){
//display an error message
String errorMessage = "Whoops - your device doesn't support capturing images!";
Toast toast = Toast.makeText(getActivity(), errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}
});
而作为从相机捕捉下面代码
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if(requestCode == CAPTURE_IMAGE) {
performCrop();
}
else if(requestCode == PIC_CROP){
//get the returned data
Bundle extras = data.getExtras();
//get the cropped bitmap
Bitmap thePic = extras.getParcelable("data");
picturePath = file.getAbsolutePath();
try {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
thePic.compress(Bitmap.CompressFormat.JPEG, 80, bytes);
file.createNewFile();
FileOutputStream out = new FileOutputStream(file);
out.write(bytes.toByteArray());
out.close();
} catch (Exception e) {
e.printStackTrace();
}
//retrieve a reference to the ImageView
//ImageView picView = (ImageView)findViewById(R.id.picture);
//display the returned cropped image
imgView.setImageBitmap(thePic);
}
try {
}catch (Exception e) {
Toast.makeText(getActivity(), "Maaf gagal mengambil foto.", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
}
声明OnCreateView外部作为一个空字符串变量picturePath林书面respon的按钮。 问题是,每当我运行应用程序并捕获图像。图像没有立即显示在画廊中,而是我需要重新运行应用程序(通过android studio)在图库中查看图像。看起来像oncreateview内的东西触发事件。但我仍然无法弄清楚什么。
请帮我解决这个问题。由于
我改变了我的问题,,,我应该在哪里申报上面的代码? – BrenDonie
试过我们的代码stil没有显示/保存在Android图库。但在我的应用程序中显示图像 – BrenDonie
哦,把它放在onActivityResult。好的工作....非常感谢你:) – BrenDonie
