自定义Dialog

布局文件

一些工具方法

    /**
     * 从控件的顶部移动到控件所在位置
     *
     * @return
     */
    public static TranslateAnimation moveToViewLocationFromTop() {
        TranslateAnimation mHiddenAction = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0.0f,
                Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
                -1.0f, Animation.RELATIVE_TO_SELF, 0.0f);
        mHiddenAction.setDuration(500);
        return mHiddenAction;
    }


    /**
     * 截取当前屏幕
     * @param activity
     * @return
     */
    public Bitmap getScreenShot(Activity activity) {
        // 获取windows中最顶层的view
        View view = activity.getWindow().getDecorView();
        view.buildDrawingCache();

        // 获取状态栏高度
        Rect rect = new Rect();
        view.getWindowVisibleDisplayFrame(rect);
        int statusBarHeights = rect.top;
        Display display = activity.getWindowManager().getDefaultDisplay();

        // 获取屏幕宽和高
        int widths = display.getWidth();
        int heights = display.getHeight();

        // 允许当前窗口保存缓存信息
        view.setDrawingCacheEnabled(true);

        // 去掉状态栏
        Bitmap bmp = Bitmap.createBitmap(view.getDrawingCache(), 0,
                0, widths, heights);

        // 销毁缓存信息
        view.destroyDrawingCache();

        return bmp;
    }


    /**
     * 改变bitmap宽高
     * @param bm
     * @param f
     * @return
     */
    public  Bitmap zoomImg(Bitmap bm,float f){

        int width = bm.getWidth();
        int height = bm.getHeight();

        float scaleWidth = f;
        float scaleHeight = f;

        Matrix matrix = new Matrix();
        matrix.postScale(scaleWidth, scaleHeight);

        Bitmap newbm = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, true);
        return newbm;
    }

接口

public interface SinaSendDialog {

    void onNormalClick();

    void onTimeClick();

    void onMapClick();
}

基本讲一下逻辑，背景采用截屏高斯模糊处理，这里一定要降图片质量，不然会慢，按钮采用一个动画从上向下划出，虽然不是特别完美，但是多少有个样子，希望高人指点

最后贴出Demo
