gerundet Image nicht nach Ressource gezeigt hinzufügen

Question

dies ist meine Klasse für Make Imageview gerundet

package customfonts; 


import android.annotation.SuppressLint;

import android.widget.ImageView; 

public class RoundedImageView extends ImageView 
{ 
    private int borderWidth = 0; 
    private int viewWidth; 
    private int viewHeight; 
    private Bitmap image; 
    private Paint paint; 
    private Paint paintBorder; 
    private BitmapShader shader; 

    public RoundedImageView(Context context) 
    { 
     super(context); 
     setup(); 
    } 

    public RoundedImageView(Context context, AttributeSet attrs) 
    { 
     super(context, attrs); 
     setup(); 
    } 

    public RoundedImageView(Context context, AttributeSet attrs, int defStyle) 
    { 
     super(context, attrs, defStyle); 
     setup(); 
    } 

    private void setup() 
    { 
     // init paint 
     paint = new Paint(); 
     paint.setAntiAlias(true); 

     paintBorder = new Paint(); 
     setBorderColor(Color.WHITE); 
     //setBorderColor(1); 
     paintBorder.setAntiAlias(true); 
     this.setLayerType(LAYER_TYPE_SOFTWARE, paintBorder); 
     paintBorder.setShadowLayer(2.0f, 0.0f, 2.0f, Color.BLACK); 
    } 

    public void setBorderWidth(int borderWidth) 
    { 
     this.borderWidth = borderWidth; 
     this.invalidate(); 
    } 

    public void setBorderColor(int borderColor) 
    { 
     if (paintBorder != null) 
      paintBorder.setColor(borderColor); 

     this.invalidate(); 
    } 

    private void loadBitmap() 
    { 
     BitmapDrawable bitmapDrawable = (BitmapDrawable) this.getDrawable(); 

     if (bitmapDrawable != null) 
      image = bitmapDrawable.getBitmap(); 
    } 

    @SuppressLint("DrawAllocation") 

    @Override 
    public void onDraw(Canvas canvas)

     // load the bitmap 
     loadBitmap(); 

     // init shader 
     if (image != null) 
     { 
      shader = new BitmapShader(Bitmap.createScaledBitmap(image, canvas.getWidth(), canvas.getHeight(), false), Shader.TileMode.CLAMP, Shader.TileMode.CLAMP); 
      paint.setShader(shader); 
      int circleCenter = viewWidth/2; 

      // circleCenter is the x or y of the view's center 
      // radius is the radius in pixels of the cirle to be drawn 
      // paint contains the shader that will texture the shape 
      canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, circleCenter + borderWidth - 4.0f, paintBorder); 
      canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, circleCenter - 4.0f, paint); 
     } 
    } 

    @Override 
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) 
    { 
     int width = measureWidth(widthMeasureSpec); 
     int height = measureHeight(heightMeasureSpec, widthMeasureSpec); 

     viewWidth = width - (borderWidth * 2); 
     viewHeight = height - (borderWidth * 2); 

     setMeasuredDimension(width, height); 
    } 

    private int measureWidth(int measureSpec) 
    { 
     int result = 0; 
     int specMode = MeasureSpec.getMode(measureSpec); 
     int specSize = MeasureSpec.getSize(measureSpec); 

     if (specMode == MeasureSpec.EXACTLY) 
     { 
      // We were told how big to be 
      result = specSize; 
     } 
     else 
     { 
      // Measure the text 
      result = viewWidth; 
     } 

     return result; 
    } 

    private int measureHeight(int measureSpecHeight, int measureSpecWidth) 
    { 
     int result = 0; 
     int specMode = MeasureSpec.getMode(measureSpecHeight); 
     int specSize = MeasureSpec.getSize(measureSpecHeight); 

     if (specMode == MeasureSpec.EXACTLY) 
     { 
      // We were told how big to be 
      result = specSize; 
     } 
     else 
     { 
      // Measure the text (beware: ascent is a negative number) 
      result = viewHeight; 
     } 

     return (result + 2); 
    } 
} 

jetzt habe ich es in xml verwenden

  <customfonts.RoundedImageView 
      android:id="@+id/profile" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:src="@drawable/photo" 
      /> 

ich versuche auch verwenden

android:background="@drawable/photo" 

und wenn ich customfonts.RoundedImageView mit ImageView seine Arbeit benutze oder ersetze und mein Bild zeige, was das Problem ith Tinte es auf meinem Klassenkode, bevor ich es update es Arbeit nach dem Update es und fügen Sie etwas Schatten seine Arbeit aufhören, jede Lösung?

Foto für Ergebnis

Answer 1

ist, dass resouce zur Verfügung?

  android:src="@drawable/photo" 

versuchen, Hardcode Höhe und Breite für Testzwecke hinzuzufügen.

  android:layout_width="120dp" 
     android:layout_height="120dp" 

Wenn es funktioniert dann überprüfen Sie Ihre Aktivität xml Architektur. Es kann sein, dass die Layouts nicht übereinstimmen.
