imageview

I have ImageView and I want to share its image. Following is my code, btshare.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { View content = findViewById(R.id.full_image_view); content.setDrawingCacheEnabled(true); Bitmap bitmap = content.getDrawingCache(); File root = Environment.getExternalStorageDirectory(); File cachePath = new File(root.getAbsolutePath() + "/DCIM/Camera/image.jpg"); try { root.createNewFile(); FileOutputStream ostream = new FileOutputStream(root); bitmap.compress(CompressFormat.JPEG, 100, ostream); ostream.close(); } catch (Exception e)

/** * @param bitmap * The source bitmap. * @param opacity * a value between 0 (completely transparent) and 255 (completely * opaque). * @return The opacity-adjusted bitmap. If the source bitmap is mutable it * will be adjusted and returned, otherwise a new bitmap is created. * Source : http://stackoverflow.com/questions/7392062/android- * semitransparent-bitmap-background-is-black/14858913#14858913 */ private Bitmap adjustOpacity(Bitmap bitmap, int opacity) { Bitmap mutableBitmap = bitmap.isMutable() ? bitmap : bitmap.copy(Bitmap.Config.ARGB_8888, true); Canvas canvas = new Canvas

I want to display a text over an Image View. I do it like Alesqui suggested here: Android Text over image The preview in Android studio looks fine: But my actual result looks like this with the text unwantedly above: I have to add the following XML dynamically to a LinearLayout during the execution: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/relativelayout" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ImageView android:id="@+id/myImageView" android:layout_width="wrap_content" android:layout_height="wrap_content"

I have a JSON string, say a name and a Url . I need to extract name into the TextView and extract and display image in ImageView . Below is the code for above scenario. public static final String JSON_STRING="{\"WebImages\":{\"Imagename\":\"image_name\",\"imageurl\":http://www.example.com/image/example.png}}"; I need to display the name in TextView which I created, and fetch the image from that url and display in the Imageview . First of all use Gson to parse Json and get url as a String, then you can use UniversalImageLoader library (it does the async image download and very easy to use)
