How Can I edit image to android gallery and save - imageview

Question

I access the android gallery and select image. after view photo on image view ..
this code is true work.
targetImage = (ImageView)findViewById(R.id.imageView1);
public void Onclickimage(View view){
try{
Intent intent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 0);
}
catch (Exception ex)
{
Toast.makeText(this,ex.getMessage(),Toast.LENGTH_LONG).show();
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0 && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
picturePath = cursor.getString(columnIndex);
cursor.close();
targetImage.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
I would like another buttonclick set text on photo to imageview.
This code does not work.
public void onClick(View view) {
Bitmap bmp = drawTextToBitmap(MainActivity.this,R.id.imageView1,"MyText");
targetImage.setImageBitmap(bmp);
}
public Bitmap drawTextToBitmap(Context mContext, int resourceId, String mText) {
try {
Resources resources = mContext.getResources();
float scale = resources.getDisplayMetrics().density;
ImageView img = (ImageView)findViewById(R.id.imageView1);
float xson = img.getWidth();
float yson = img.getHeight();
Bitmap bitmap = BitmapFactory.decodeResource(resources, resourceId);
android.graphics.Bitmap.Config bitmapConfig = bitmap.getConfig();
// set default bitmap config if none
if(bitmapConfig == null) {
bitmapConfig = android.graphics.Bitmap.Config.ARGB_8888;
}
// resource bitmaps are imutable,
// so we need to convert it to mutable one
bitmap = bitmap.copy(bitmapConfig, true);
Canvas canvas = new Canvas(bitmap);
// new antialised Paint
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
// text color - #3D3D3D
paint.setColor(Color.BLACK);
// text size in pixels
paint.setTextSize((int) (12 * scale));
// text shadow
paint.setShadowLayer(1f, 0f, 1f, Color.DKGRAY);
// draw text to the Canvas center
Rect bounds = new Rect();
paint.getTextBounds(mText, 0, mText.length(), bounds);
int x = (bitmap.getWidth() - bounds.width())/4;
int y = ((bitmap.getHeight() + bounds.height())/3)+50;
paint.setColor(Color.RED);
canvas.drawRect(x * scale-15, y * scale-30,xson+15 - x * scale , yson, paint); // for background
paint.setColor(Color.BLACK); for text
canvas.drawText(mText, x * scale, y * scale, paint);
return bitmap;
} catch (Exception e) {
Toast.makeText(MainActivity.this,e.toString(),Toast.LENGTH_LONG).show();
return null;
}
I write R.id.imageview1 instead to R.drawable.recimage this code is work but for just one photo.

Answer 1

I solve the problem
this code is wrong
Bitmap bitmap = BitmapFactory.decodeResource(resources, resourceId);
true code
img.setDrawingCacheEnabled(true);
Bitmap bitmap = img.getDrawingCache();
