shadow샘플

bitmap파일로 구현한 shadow샘플 예제 입니다.

TestView.java

public class TestView extends View {  private Context mContext;  Bitmap sampleBitmap, sampleLine;  int mWidth;  int mHeight;  ImageView imageView;    public TestView(Context context) {   super(context);     this.mContext = context;      setWillNotDraw(false);      sampleBitmap = BitmapFactory.decodeResource( this.getResources(),      R.drawable.test);   sampleLine = BitmapFactory.decodeResource( this.getResources(),      R.drawable.testline);   mWidth = sampleBitmap.getWidth();   mHeight = sampleBitmap.getHeight();     }        @Override  protected void onDraw(Canvas canvas) {         drawBlackRect(canvas,sampleBitmap.getWidth(),sampleBitmap.getHeight(),10);      Paint p = new Paint(Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG);      //p.setShadowLayer(3,0,0,0xffffffff);   p.setShadowLayer(10,0,0,android.graphics.Color.BLACK);   p.setColor(android.graphics.Color.BLACK);   canvas.drawBitmap(sampleBitmap, 10.0f,10.0f,null);     //canvas.drawBitmap(sampleLine, 5.0f,5.0f, null);         DrawLayoutLine(canvas);   super.onDraw(canvas);  }      private void drawBlackRect(Canvas canvas,int width, int height, int startDraw){   Paint aa = new Paint();   //aa.setShadowLayer(5,0,0,android.graphics.Color.BLACK);              int distance =29;      Rect endR = new Rect();   endR.left = startDraw-distance;   endR.right = startDraw+ width+distance+1;   endR.top = startDraw-distance;   endR.bottom = startDraw + height+distance-2;         canvas.drawBitmap(sampleLine, null, endR, aa);      }      private void DrawLayoutLine(Canvas canvas){   setWillNotDraw(false);    DashPathEffect dashPath = new DashPathEffect(new float[]{8,3}, 1);       Paint paint = new Paint();         paint.setColor(android.graphics.Color.BLACK);         //paint.setShadowLayer(5f,2f, 10f, 8);                //paint.setShader(shader)         paint.setPathEffect(dashPath);         paint.setStrokeWidth(1);      canvas.drawLine(0, 0, this.getWidth() - 1, 0, paint);   canvas.drawLine(0, 0, 0, this.getHeight() - 10, paint);   canvas.drawLine(this.getWidth() - 1, 0, this.getWidth() - 1, this     .getHeight() - 1, paint);   canvas.drawLine(0, this.getHeight() - 1, this.getWidth() - 1, this     .getHeight() - 1, paint);     }    @Override  protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {          super.onMeasure(widthMeasureSpec, heightMeasureSpec);   Log.i("viewImage measure","viewImae measure");   if(mWidth!=0 && mHeight !=0){    int width = MeasureSpec.getSize(mWidth + 40);    int height = MeasureSpec.getSize(mHeight + 40);    setMeasuredDimension(width, height);    Log.i("size Control","size Control");   }  }     }

ShadowSample.java

public class ShadowSample extends Activity {     /** Called when the activity is first created. */      LinearLayout layout;  LayoutParams layoutParams;      @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);                          layout = (LinearLayout)findViewById(R.id.layout);         layoutParams = new LayoutParams(LayoutParams.WRAP_CONTENT,     LayoutParams.WRAP_CONTENT);         TestView viewTest = new TestView(this);         layout.addView(viewTest);                     }         }
