以下方法为限制dialog的最小宽度以及最大高度，可以通过修改判断条件来控制最小或最大

    /**
     * 在dialog.show()前调用此方法
     * @param mView  dialog要显示的view
     */
    private void setDialogSize(final View mView){
        mView.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
            @Override
            public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop,
                                       int oldRight, int oldBottom) {
                int heightNow = v.getHeight();//dialog当前的高度
                int widthNow = v.getWidth();//dialog当前的宽度
                int needWidth = (int) (getWindowManager().getDefaultDisplay().getWidth() * 0.7);//最小宽度为屏幕的0.7倍
                int needHeight = (int) (getWindowManager().getDefaultDisplay().getHeight() * 0.6);//最大高度为屏幕的0.6倍
                if (widthNow < needWidth || heightNow > needHeight){
                    if (widthNow > needWidth){
                        needWidth = FrameLayout.LayoutParams.WRAP_CONTENT;
                    }
                    if (heightNow < needHeight){
                        needHeight = FrameLayout.LayoutParams.WRAP_CONTENT;
                    }
                    mView.setLayoutParams(new FrameLayout.LayoutParams(needWidth,
                            needHeight));
                }
            }
        });
    }
