любая помощь?

даже с кодом с вне XML

Answer 1

Г-н sisara стираться ваш взгляд попробовать этот код сделал некоторые кодирования для вас

public class MainActivity extends Activity { 
    private ImageView imViewAndroid; 

    private TextView discriptionn; 
    private TextView statusText; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.test_layout); 
     imViewAndroid = (ImageView) findViewById(R.id.image); 

     discriptionn = (TextView) findViewById(R.id.discription); 
     statusText = addStatusText((ViewGroup) findViewById(R.id.relative_layout_down)); 
     applyBlur(); 


    } 

    private void applyBlur() { 
     imViewAndroid.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() { 
      @Override 
      public boolean onPreDraw() { 
       imViewAndroid.getViewTreeObserver().removeOnPreDrawListener(this); 
       imViewAndroid.buildDrawingCache(); 

       Bitmap bmp = imViewAndroid.getDrawingCache(); 
       blur(bmp, discriptionn); 
       return true; 
      } 
     }); 
    } 

    @TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1) 
    private void blur(Bitmap bkg, View view) { 
     long startMs = System.currentTimeMillis(); 

     float radius = 20; 

     Bitmap overlay = Bitmap.createBitmap((int) (view.getMeasuredWidth()), 
       (int) (view.getMeasuredHeight()), Bitmap.Config.ARGB_8888); 

     Canvas canvas = new Canvas(overlay); 

     canvas.translate(-view.getLeft(), -view.getTop()); 
     canvas.drawBitmap(bkg, 0, 0, null); 

     RenderScript rs = RenderScript.create(MainActivity.this); 

     Allocation overlayAlloc = Allocation.createFromBitmap(
       rs, overlay); 

     ScriptIntrinsicBlur blur = ScriptIntrinsicBlur.create(
       rs, overlayAlloc.getElement()); 

     blur.setInput(overlayAlloc); 

     blur.setRadius(radius); 

     blur.forEach(overlayAlloc); 

     overlayAlloc.copyTo(overlay); 

     view.setBackground(new BitmapDrawable(
       getResources(), overlay)); 

     rs.destroy(); 
     statusText.setText(System.currentTimeMillis() - startMs + "ms"); 
    } 

    @Override 
    public String toString() { 
     return "RenderScript"; 
    } 

    private TextView addStatusText(ViewGroup container) { 
     TextView result = new TextView(MainActivity.this); 
     result.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); 
     result.setTextColor(0xFFFFFFFF); 
     container.addView(result); 
     return result; 
    } 
}

Попробуйте это в XML

android:alpha="0.5" 

или в коде

yourView.getBackground().setAlpha(100); 

Попробуйте этот код
