Android: Tabstyle | 易学教程

问题

I have been trying to make a tabstyle that looks like this. But so far it doesn't work Can someone help me with this..

http://www.technobuzz.net/wp-content/uploads/2010/02/seesmic-android-260-208.png

The style shows only the colors When selected. When I use a white icon is the text (text setindicator) white. This also applies to the gray icon.

When the icon color is white the text from the setindicator is then also white.. How can I fix this.

Thanks in advance!

Main.java

intent = new Intent().setClass(this, Settings.class);
         spec = tabHost.newTabSpec("settings").setIndicator("Settings",
                res.getDrawable(R.drawable.tab_settings))
                .setContent(intent);
                tabHost.addTab(spec);


                TabWidget tw = getTabWidget(); 
                for (int i = 0; i < tw.getChildCount(); i++) { 
                        View v = tw.getChildAt(i); 
                        v.setBackgroundDrawable(getResources().getDrawable 
                        (R.drawable.custom_tab)); 
                }

tab_settings

  <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- PRESSED TAB -->
    <item 
        android:state_pressed="true"
        android:drawable="@drawable/artists_on"
        android:color="#bfbfbf"
        />
    <!-- INACTIVE TABS -->
    <item

There's four states for the background of your tabs - you have almost all of them:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item <!-- PRESSED TAB -->
        android:state_pressed="true"
        android:drawable="@drawable/minitab_pressed"
        />
    <item <!-- INACTIVE TABS -->
        android:state_selected="false"
        android:state_focused="false"
        android:state_pressed="false"
        android:drawable="@drawable/minitab_unselected"
        />
    <item <!-- ACTIVE TAB -->
        android:state_selected="true"
        android:state_focused="false"
        android:state_pressed="false"
        android:drawable="@drawable/minitab_default"
        />
    <item <!-- SELECTED TAB -->
        android:state_focused="true"
        android:state_selected="true"
        android:state_pressed="false"
        android:drawable="@drawable/minitab_selected"
        />
</selector>

For text color, you need to create a selector as well and assign this drawable as the textColor:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:color="@color/white" />
    <item android:state_focused="true" android:color="@color/white" />
    <item android:state_pressed="true" android:color="@color/white" />
    <item android:color="#bfbfbf" />
</selector>
