Question

我想在选项卡中添加选择器。喜欢每个标签的select_image和unselect_image。我是这样做的。

此特定代码正在为TabActivity

运行

public class MainActivity extends FragmentActivity
{
    private FragmentTabHost mTabHost;

    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);

        mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);


        TabSpec spec;

        Intent intent;

        View saveView = LayoutInflater.from(MainActivity.this).inflate(R.layout.tab_save_btn,null);



        intent = new Intent(MainActivity.this, Save.class);

        spec = mTabHost.newTabSpec("SAVE").setIndicator(saveView)
                .setContent(intent);

        mTabHost.addTab(spec);



        View chargeView = LayoutInflater.from(MainActivity.this).inflate(R.layout.tab_charge_btn, null);

        intent = new Intent(MainActivity.this, Charge.class);

        spec = mTabHost.newTabSpec("CHARGE").setIndicator(chargeView)
                .setContent(intent);

        mTabHost.addTab(spec);


        View rankView = LayoutInflater.from(MainActivity.this).inflate(R.layout.tab_rank_btn, null);

        intent = new Intent(MainActivity.this, RankFragment.class);

        spec = mTabHost.newTabSpec("RANK").setIndicator(rankView)
                .setContent(intent);

        mTabHost.addTab(spec);

        mTabHost.setCurrentTab(1);

    }
}

tab_save_btn.xml

<?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" >

    <ImageView
        android:id="@+id/save_tab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:background="@drawable/save_selector" />

</RelativeLayout>

save_selector

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/home_selected" android:state_selected="true"></item>
    <item android:drawable="@drawable/home_unselect" android:state_selected="false"></item>

</selector>

它给了我多个错误。 TabActivity运行相同的代码。

错误说tabhost.setUp必须调用，需要上下文和 FragmentManager作为参数。

您是否忘记调用tabhost.setup（LocalActivityManager activityGroup）

我在哪里做错了？

activity_main.xml中

<?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" >

    <FrameLayout
        android:id="@+id/realtabcontent"
        android:layout_width="match_parent"
        android:layout_height="0dip"
        android:layout_weight="1" />

    <android.support.v4.app.FragmentTabHost
        android:id="@android:id/tabhost"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_weight="0" />
    </android.support.v4.app.FragmentTabHost>

</LinearLayout>

试试这个

    mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
             mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
         View saveView = LayoutInflater.from(MainActivity.this).inflate(R.layout.tab_save_btn,null);
        mTabHost.addTab(mTabHost.newTabSpec("SAVE").setIndicator(saveView ),SaveFragment.class, null);
      View chargeView = LayoutInflater.from(MainActivity.this).inflate(R.layout.tab_charge_btn, null);

        mTabHost.addTab(mTabHost.newTabSpec("CHARGE").setIndicator(chargeView ),ChargeFragment.class, null);
    .....
    ...........

        mTabHost.setCurrentTab(1);

将选择器图像添加到fragmentTabHost
