1、開發Android TV APP, 使用遙控器選中按鈕或者選著其它菜單

如果沒有高亮顯示,就看不出選中哪個按鈕或者菜單

2、在drawable 添加 border_red.xml 設定選中高亮

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android">    <corners android:radius="2dp"/>    <stroke        android:color="#FF0000"        android:width="3dp" />    <solid android:color="#00FF0000" /></shape>
View Code

3、在 layout 添加頁面xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <RelativeLayout        android:focusable="false"        android:gravity="center"        android:layout_gravity="center"        android:clipToPadding="false"        android:clipChildren="false"        android:id="@+id/main"        android:layout_width="match_parent"        android:layout_height="wrap_content">        <Button            android:id="@+id/button_id_1"            android:layout_width="match_parent"            android:gravity="center"            android:layout_height="wrap_content"            android:background="#303F9F"            android:focusableInTouchMode="true"            android:textColor="#FFF"            android:layout_marginTop="10dp"            android:layout_marginLeft="0dp"            android:text="按鈕"            android:textSize="60dp"            />        <Button            android:id="@+id/button_id_2"            android:layout_below="@id/button_id_1"            android:layout_width="match_parent"            android:gravity="center"            android:layout_height="wrap_content"            android:background="#303F9F"            android:focusableInTouchMode="true"            android:textColor="#FFF"            android:text="按鈕"            android:layout_marginTop="30dp"            android:textSize="60dp"            />        <Button            android:id="@+id/button_id_3"            android:layout_width="match_parent"            android:gravity="center"            android:layout_height="wrap_content"            android:background="#303F9F"            android:layout_below="@id/button_id_2"            android:focusableInTouchMode="true"            android:textColor="#FFF"            android:text="按鈕"            android:layout_marginTop="30dp"            android:textSize="60dp"            />    </RelativeLayout></LinearLayout>

 4、添加選中高亮顯示,設定焦點控制

  BorderView border = new BorderView(this);        border.setBackgroundResource(R.drawable.border_red);        main = (RelativeLayout) findViewById(R.id.main);        border.attachTo(main);
View Code
