Popuwindow簡單使用

今天使用popuwindow進行簡單的第三方分享。以前用自帶的圖案，現在要求自己寫自定義的界面，於是用popouwindow，發現裏面的坑還是挺多的

 mpopuwindow = new PopupWindow();
        final View mView = LayoutInflater.from(this).inflate(R.layout.popuwindows_share, null);
        RadioButton mQQ = (RadioButton) mView.findViewById(R.id.rb_qq);
        RadioButton mWeiXi = (RadioButton) mView.findViewById(R.id.rb_weixin);
        RadioButton mWeiBo = (RadioButton) mView.findViewById(R.id.rb_weibo);
        Button mbt_share_popu = (Button) mView.findViewById(R.id.bt_share_popu);
        mpopuwindow.setContentView(mView);
        mpopuwindow.setWidth(RelativeLayout.LayoutParams.MATCH_PARENT);
        mpopuwindow.setHeight(RelativeLayout.LayoutParams.WRAP_CONTENT);
        mpopuwindow.setAnimationStyle(R.style.anim_menu_bottombar);
        mpopuwindow.setFocusable(true);//獲取焦點
        final ColorDrawable dw = new ColorDrawable(0xb0000000);
        mpopuwindow.setBackgroundDrawable(dw);
        mpopuwindow.showAtLocation(mView, Gravity.BOTTOM, 0, 0);
        mpopuwindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
            //檢測popuwindwo消失
            @Override
            public void onDismiss() {
                dismiss();
            }
        });
        mView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                dismiss();
                return false;
            }
        });

這個是簡單的佈局頁面

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom">


    <TextView
        android:id="@+id/tv_share"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/rg_group"
        android:background="@color/white"
        android:gravity="center"
        android:padding="10dp"
        android:text="分享給朋友"
        android:textColor="@color/black"
        android:textSize="22sp" />

    <RadioGroup
        android:id="@+id/rg_group"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/view"
        android:background="@color/white"
        android:orientation="horizontal"
        android:padding="10dp">

        <RadioButton
            android:id="@+id/rb_weibo"
            style="@style/TabBottomStyle"
            android:drawableTop="@mipmap/weibo"
            android:text="微博" />

        <RadioButton
            android:id="@+id/rb_weixin"
            style="@style/TabBottomStyle"
            android:drawableTop="@mipmap/weixin"
            android:text="微信" />

        <RadioButton
            android:id="@+id/rb_qq"
            style="@style/TabBottomStyle"
            android:drawableTop="@mipmap/qq"
            android:text="QQ" />
    </RadioGroup>

    <View
        android:id="@+id/view"
        android:layout_width="match_parent"
        android:layout_height="3px"
        android:layout_above="@+id/bt_share_popu"
        android:background="@color/home_line" />

    <Button
        android:id="@+id/bt_share_popu"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:background="@color/white"
        android:gravity="center"
        android:padding="15dip"
        android:text="取消" />
</RelativeLayout>

這個是style裏面的屬性

<style name="TabBottomStyle">
        <item name="android:layout_width">wrap_content</item>
        <item name="android:layout_height">wrap_content</item>
        <item name="android:layout_gravity">center_vertical</item>
        <item name="android:layout_weight">1</item>
        <item name="android:background">@android:color/transparent</item>
        <item name="android:button">@null</item>
        <item name="android:gravity">center</item>
        <item name="android:textColor">@android:color/darker_gray</item>
        <item name="android:drawablePadding">5dp</item>
        <item name="android:padding">5dp</item>
        <item name="android:textSize">14sp</item>
</style>
