PopupWindow 从底部弹出窗体

第一步  : 初始化PopupWindow

    private void initPop() {

        if (view == null) {

            // 照片

            view = View.inflate(RegisterActivity.this, R.layout.pop_phone, null);   / /加载对象

        }

        if (mPopupWindow == null) {

            mPopupWindow = new PopupWindow(view, LayoutParams.MATCH_PARENT,

                    LayoutParams.WRAP_CONTENT, true);

        }

    }

第二步 ,点击事件打开开

    // 打开pop

    private void openPopup() {

        mPopupWindow.setBackgroundDrawable(new ColorDrawable(Color

                .parseColor("#b0000000")));  //设置背景颜色

        mPopupWindow.showAtLocation(register_lay_out, Gravity.BOTTOM, 0, 0);

        mPopupWindow.setAnimationStyle(R.style.app_pop);

        mPopupWindow.setOutsideTouchable(true);   //点击外面关闭

        mPopupWindow.setFocusable(true);    //得到焦点

        mPopupWindow.update();

      }

R.style.app_pop

    <style name="AppTheme" parent="android:Theme.Light" />

        <style name="app_pop">

        <item name="android:windowEnterAnimation">@anim/pop_up</item>

        <item name="android:windowExitAnimation">@anim/pop_down</item>

    </style>

pop_up.xml

<?xml version="1.0" encoding="utf-8"?>

<translate xmlns:android="http://schemas.android.com/apk/res/android"

    android:fromXDelta="0"

    android:toXDelta="0"

    android:fromYDelta="100%"

    android:toYDelta="0%"

    android:duration="200">

</translate>

pop_down.xml

<?xml version="1.0" encoding="utf-8"?>

<translate xmlns:android="http://schemas.android.com/apk/res/android"

    android:fromXDelta="0"

    android:toXDelta="0"

    android:fromYDelta="0%"

    android:toYDelta="100%"

    android:duration="200">

</translate>

附录 :打开前 先判断 关闭

    private void dismissPopupWindow() {

        // 把旧的弹出窗体关闭掉。

        if (mPopupWindow != null && mPopupWindow.isShowing()) {

            mPopupWindow.dismiss();

            // mPopupWindow = null;

        }

    }
