接下来就是一波贴代码的过程

自定义Dialog

public class SinaSendView extends Dialog {
  private ImageButton ib_dialog_sina_close;
  private LinearLayout ll_dialog_sina_write;
  private LinearLayout ll_dialog_sina_time;
  private LinearLayout ll_dialog_sina_map;
  private LinearLayout ll_dialog_sina_menu;
  private ImageView iv_dialog_sina_bg,iv_dialog_sina_des;
  private Context mContext;
  private Boolean hideDes;
  private Bitmap screenShot;
  private Bitmap bitmap;
  private ByteArrayOutputStream baos;
  private byte[] bytes;

  public SinaSendView(Context context) {
    super(context);
    this.mContext = context;
  }

  public SinaSendView(Context context, int themeResId,Boolean hideDes) {
    super(context, themeResId);
    this.mContext = context;
    this.hideDes = hideDes;
  }

  protected SinaSendView(Context context, boolean cancelable, OnCancelListener cancelListener) {
    super(context, cancelable, cancelListener);
    this.mContext = context;
  }

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setContentView(R.layout.layout_sina_send_dialog);
    ib_dialog_sina_close = (ImageButton) findViewById(R.id.ib_dialog_sina_close);

    iv_dialog_sina_bg = (ImageView) findViewById(R.id.iv_dialog_sina_bg);
    iv_dialog_sina_des = (ImageView) findViewById(R.id.iv_dialog_sina_des);
    initView();
  }

  private void initView() {
    setBrulBg();
    ll_dialog_sina_menu.setVisibility(View.VISIBLE);
    ll_dialog_sina_menu.setAnimation(AnimationUtil.moveToViewLocationFromTop());
    ib_dialog_sina_close.setOnClickListener(new View.OnClickListener() {
      @Override

    });
    if(hideDes){

    }
  }

  /**
   * 设置模糊背景
   */
  private void setBrulBg(){
    screenShot = CommonUtils.getInstance().getScreenShot((Activity) mContext);
    bitmap = CommonUtils.getInstance().zoomImg(screenShot, 0.2f);
    baos = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 1, baos);
    bytes = baos.toByteArray();
    Glide.with(mContext)
        .load(bytes)
        .asBitmap()
        .transform(new BlurTransformation(CommonUtils.getInstance().getContext(), 25))
        .into(iv_dialog_sina_bg);
  }


  public void setClick(final SinaSendDialog mSinaSendDialog){
    this.show();

    ll_dialog_sina_write.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        mSinaSendDialog.onNormalClick();
        dismiss();
      }
    });

    ll_dialog_sina_map.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        mSinaSendDialog.onMapClick();
        dismiss();
      }
    });

    ll_dialog_sina_time.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        mSinaSendDialog.onTimeClick();
        dismiss();
      }
    });

  }

  @Override
  public void dismiss() {
    super.dismiss();
    if(screenShot != null && !screenShot.isRecycled()){
      screenShot.recycle();
      screenShot = null;
    }
    if(bitmap != null && !bitmap.isRecycled()){
      bitmap.recycle();
      bitmap = null;
    }
    try {
      baos.close();
    } catch (IOException e) {
      e.printStackTrace();
    }
    bytes = null;
    System.gc();
  }
}

布局文件

Style

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。
