1. 获取dailog实例

        private void showDialog() {
        Dialog dialog = new Dialog(getActivity(), R.style.BottomDialog);
    //        View contentView = LayoutInflater.from(getActivity()).inflate(R.layout.dialog_content_circle, null);
            View contentView = LayoutInflater.from(getActivity()).inflate(R.layout.dialog_content_nomal, null);
            dialog.setContentView(contentView);
            ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams) contentView.getLayoutParams();
    //        params.width = getResources().getDisplayMetrics().widthPixels - DensityUtil.dp2px(getActivity(), 16f);
    //        params.bottomMargin = DensityUtil.dp2px(getActivity(), 8f);
            params.width = getResources().getDisplayMetrics().widthPixels;
        contentView.setLayoutParams(params);
        dialog.setCanceledOnTouchOutside(true);
        dialog.getWindow().setGravity(Gravity.BOTTOM);
        dialog.getWindow().setWindowAnimations(R.style.BottomDialog_Animation);
        dialog.show();
    }
   

2. 在style中配置相关的动画和dialog主题

3. anim中dialog的动画

   • translate_dialog_in.xml

   • translate_dialog_out.xml

4. 像素转换工具类

    import android.content.Context;
    import android.util.TypedValue;

    public class DensityUtil {
        /**
         * dp转px
         *
         * @param context
         * @param dpVal
         * @return
         */
        public static int dp2px(Context context, float dpVal) {
            return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dpVal,
                    context.getResources().getDisplayMetrics());
        }
    
        /**
         * sp转px
         *
         * @param context
         * @param spVal
         * @return
         */
        public static int sp2px(Context context, float spVal) {
            return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, spVal,
                    context.getResources().getDisplayMetrics());
        }
    
        /**
         * px转dp
         *
         * @param context
         * @param pxVal
         * @return
         */
        public static float px2dp(Context context, float pxVal) {
            final float scale = context.getResources().getDisplayMetrics().density;
            return (pxVal / scale);
        }
    
        /**
         * px转sp
         *
         * @param pxVal
         * @param pxVal
         * @return
         */
        public static float px2sp(Context context, float pxVal) {
            return (pxVal / context.getResources().getDisplayMetrics().scaledDensity);
        }
    }

5. layout相关布局
