Question
Here is my camera code. I'm writing a function which use startActivityForResult
to transact the result. But when I choose ACTION_IMAGE_CAPTURE
, normally it will capture the pic and I can go and find this pic's path to use. However, I can't find the path in my mobile phone. It seems this code can't use in my phone and thus I can't save pic in my mobile phone.
My mobile phone model is SONY xperia C and SONY xperia L.
Here are my choose code
public void function()
{
AlertDialog.Builder builder = new AlertDialog.Builder(repair.this);
builder.setTitle("Please select").setPositiveButton("camera", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int i)
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 1);
}
}).setNegativeButton("album", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int i)
{
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 2);
}
}).show();
}
And here are my onActivityResult
code.
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
options.inSampleSize = calculateInSampleSize(options, 2048, 2048);
options.inJustDecodeBounds = false;
if (resultCode == RESULT_OK)
{
if (requestCode == 1 || requestCode == 2)
{
Uri photoUri = data.getData();
String[] pojo = {MediaStore.Images.Media.DATA};
Cursor cursor = managedQuery(photoUri, pojo, null, null,null);
if(cursor != null )
{
int columnIndex = cursor.getColumnIndexOrThrow(pojo[0]);
cursor.moveToFirst();
picPath = cursor.getString(columnIndex);
}
if(picPath != null && ( picPath.endsWith(".png") || picPath.endsWith(".PNG") ||picPath.endsWith(".jpg") ||picPath.endsWith(".JPG") ))
{
picPath1 = picPath;
Bitmap bm = BitmapFactory.decodeFile(picPath1, options);
imgbtnphoto1.setImageBitmap(bm);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bm.compress(CompressFormat.JPEG, 80, bos);
byte[] data1 = bos.toByteArray();
bab1 = new ByteArrayBody(data1, "img1.jpg");
}
else
{
Toast.makeText(this, "Picture type is incorrect", Toast.LENGTH_LONG).show();
}
}
else
{
Toast.makeText(this, "Please re-select the picture", Toast.LENGTH_LONG).show();
}
}
else
{
Toast.makeText(this, "Please re-select the picture", Toast.LENGTH_LONG).show();
}
super.onActivityResult(requestCode, resultCode, data);
}
Thank you so so much for your help!
Solution
This is my code to show you.
public void initView() {
AlertDialog.Builder builder = new AlertDialog.Builder(repair.this).setMessage("Select")
.setPositiveButton("Camera", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int i) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
photoUri = getOutputMediaFileUri(3);
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
startActivityForResult(intent, 1);
}
}).setNegativeButton("Album", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int i) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 2);
}
});
AlertDialog dialog = builder.show();
TextView messageText = (TextView)dialog.findViewById(android.R.id.message);
messageText.setGravity(Gravity.CENTER);
dialog.show();
}
public Uri getOutputMediaFileUri(int type){
return Uri.fromFile(getOutputMediaFile(type));
}
private static File getOutputMediaFile(int type) {
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),"Camera"); // Storage Folder
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.d("Camera", "Oops! Failed create "+ "Camera" + " directory"); // Error warning
return null;
}
}
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
File mediaFile;
if (type == 3) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".jpg"); //Storage Name
} else {
return null;
}
return mediaFile;
}
Hope it may help you.
