Android知识点六:自定义分享菜单

     首先布局：activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"     android:gravity="center_horizontal">    <Button        android:id="@+id/btn_click"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_horizontal"        android:layout_marginBottom="10dip"        android:background="@drawable/btn_black_selector"        android:focusable="false"        android:text="点击"        android:textColor="@color/white"        android:textSize="18sp" />    <RelativeLayout        android:id="@+id/myRelativeLayout"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:layout_gravity="center_horizontal"        android:background="@drawable/popup_bg_black"        android:gravity="bottom|center_horizontal"        android:orientation="vertical"         >        <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_alignParentBottom="true"            android:layout_marginLeft="10dip"            android:layout_marginRight="10dip"            android:background="@drawable/popup_bg_page"            android:orientation="vertical" >            <TextView                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:gravity="center"                android:paddingBottom="10dip"                android:paddingTop="15dip"                android:text="选择分享方式"                android:textColor="@color/white"                android:textSize="16sp" />            <com.tbkj.common.widget.GridViewInScrowView                android:id="@+id/sharetype_grid"                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:listSelector="#00000000"                android:numColumns="3" >            </com.tbkj.common.widget.GridViewInScrowView>            <Button                android:id="@+id/cancel_btn"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_gravity="center_horizontal"                android:layout_marginBottom="10dip"                android:background="@drawable/btn_black_selector"                android:focusable="false"                android:text="取消"                android:textColor="@color/white"                android:textSize="18sp" />        </LinearLayout>    </RelativeLayout></RelativeLayout>

   自定义控件GridViewInScrowView继承GridView

 

public class GridViewInScrowView extends GridView {public GridViewInScrowView(Context context) {super(context);}public GridViewInScrowView(Context context, AttributeSet attrs) {super(context, attrs);}public GridViewInScrowView(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);}@Overridepublic void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST);super.onMeasure(widthMeasureSpec, expandSpec);}}

MainActivity.java
