标签和图像的一些设备 [英] tabs and images with some devices
本文介绍了标签和图像的一些设备的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我的应用程序的一部分延伸FragmentActivity。
Part of my app extends FragmentActivity.
该标签具有图像和文本(它有3个标签,但他们也有类似的code,唯一的区别是文本和图像):
The tab has an image and a text (it has 3 tabs, but they has similar code, the only difference is the text and the image):
mTabManager.addTab("map", mTabHost.newTabSpec("map").setIndicator(context.getString(R.string.map), activity.getResources().getDrawable(R.drawable.maps_tab)), Maps.class, bundlePos);
和maps_tab.xml:
And maps_tab.xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When selected, use icon1 -->
<item android:drawable="@drawable/ic_mapa_selected"
android:state_selected="true" />
<!-- When not selected, use icon2-->
<item android:drawable="@drawable/ic_mapa_unselected" />
</selector>
好这项工作很好的一些设备如银河王牌,还是HTC野火S:
Ok this work fine in some devices as Galaxy Ace, or HTC Wildfire S:
但没有其它设备,作为GALAXY SII,银河SIII或HTC Desire的ç
But fails in other devices as Galaxy SII, Galaxy SIII or HTC Desire C
这怎么能不兼容解决?
推荐答案
下面是实现同一
TabSample.java
public class TabSample extends TabActivity {
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setTabs() ;
}
private void setTabs()
{
addTab("Home", R.drawable.tab_home, ArrowsActivity.class);
addTab("Search", R.drawable.tab_search, OptionsActivity.class);
//To add more tabs just use addTab() method here like previous line.
}
private void addTab(String labelId, int drawableId, Class<?> c)
{
TabHost tabHost = getTabHost();
Intent intent = new Intent(this, c);
TabHost.TabSpec spec = tabHost.newTabSpec("tab" + labelId);
View tabIndicator = LayoutInflater.from(this).inflate(R.layout.tab_indicator, getTabWidget(), false);
TextView title = (TextView) tabIndicator.findViewById(R.id.title);
title.setText(labelId);
ImageView icon = (ImageView) tabIndicator.findViewById(R.id.icon);
icon.setImageResource(drawableId);
spec.setIndicator(tabIndicator);
spec.setContent(intent);
tabHost.addTab(spec);
int i = tabHost.getCurrentTab();
Toast.makeText(TabSample.this, "tab->" + i,Toast.LENGTH_SHORT).show();
}
}
的main.xml
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<FrameLayout android:id="@android:id/tabcontent"
android:layout_width="fill_parent" android:layout_height="0dip"
android:layout_weight="1" />
<TabWidget android:id="@android:id/tabs"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="0" />
</LinearLayout>
</TabHost>
tab_indicator.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="0dip"
android:layout_height="55dip"
android:layout_weight="1"
android:orientation="vertical"
android:background="@drawable/tab_indicator"
android:padding="5dp">
<ImageView android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:src="@drawable/icon"
/>
<TextView android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
style="?android:attr/tabWidgetStyle"
/>
</RelativeLayout>
