pinned

Android实现 某一个区域 的 Pin效果

原理图解：

代码集成：

• 下载或复制ScrollViewWithPinnedView类添加为自定义控件类
• 在布局文件中引入该控件
• 在Activity的OnCreate方法中设置该控件的pinned区域

示例：

• 布局文件example_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
    
    <your.company.ScrollViewWithPinnedView
        android:id="@+id/main_scroll"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >
        
        <LinearLayout
            android:id="@+id/pinned"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:background="#ffacacac" >

            <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="pinned view here" />

            <TextView
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="awesome" />

            <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="pinned view here" />
        </LinearLayout>
        
    </your.company.ScrollViewWithPinnedView>

 </LinearLayout>

• Activity Class ExampleActivity.java

onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.example_layout);
    
    mScrollWithPinnedView = (ScrollViewWithPinnedView)findViewById(R.id.yourscrollid))
    mScrollWithPinnedView.setPinnedView(this.findViewById(R.id.pinned));
}
