  2. Then use RecyclerView GridLayoutManager grid layout display, their own click events are almost complete

Simple implementation

  • Write a layout for the sharing interface

    <LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="16dp"
        android:text="I am the Advertising column."
        android:textAppearance="@style/TextAppearance.AppCompat"
        android:textSize="18sp"/>

    <View
        android:layout_width="match_parent"
        android:layout_height="1px"
        android:background="@android:color/darker_gray"/>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/list_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</LinearLayout>Copy the code

  • Display in the Activity using the BottomSheetDialog control

    BottomSheetDialog mBottomSheetDialog = new BottomSheetDialog(this);
mBottomSheetDialog.setContentView(R.layout.dialog_bottom_sheet);
mBottomSheetDialog.show();Copy the code

  • Write a RecyclerViewAdapter and appinfo_item layout

    <LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:orientation="vertical">

    <ImageView
        android:id="@+id/img_list_item"
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:scaleType="centerCrop"
        tools:src="@mipmap/ic_launcher"/>

    <TextView
        android:id="@+id/text_list_item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="2dp"
        android:ellipsize="end"
        android:singleLine="true"
        tools:text=Share "11111111111111"/>
</LinearLayout>Copy the code

  • Get a list of all the apps on your phone that support sharing

    public static List<ResolveInfo> getShareApps(Context context, Intent intent) {
        List<ResolveInfo> resolveInfoList;
        PackageManager pm = context.getPackageManager();
        resolveInfoList = pm.queryIntentActivities(intent, PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);
        return resolveInfoList;
    }Copy the code

  • Return the data to the Activity, and then set up the Adapter. See ZhihuShareDialog for the code

disadvantages

  • Applications obtained through PackageManager’s queryIntentActivities method are in the order in which they are installed, while Lollipop(5.0) has support for native sharing to automatically rank frequently used applications at the top. Of course, you can also implement your own application sorting, but more difficult, you can refer to the source code ResolverActivity

    ​

advantages

  • You can customize the sharing interface, such as adding advertising columns like Zhihu, designing a set of your own UI, setting the order of applications, and so on
