Android 默認Tab標簽大小及間距修改

一般來說，我都是用Android默認的Tab，但此時Android會根據你增加的Tab頁面平均分配Tab標簽，假如你只有兩個Tab，那么長度將會很長，并且其高度略微過高，并不好看，網上解決這個問題有些是自定義Tab。我們仍然使用默認的Tab解決此問題。

修改前 代碼、圖片如下：

?

import?android.app.TabActivity;??
import?android.graphics.Color;??
import?android.os.Bundle;??
import?android.view.LayoutInflater;??
import?android.widget.TabHost;??
import?android.widget.TabHost.OnTabChangeListener;??
??
public?class?MyTab?extends?TabActivity?implements?OnTabChangeListener?{??
??
????private?TabHost?myTabhost;??
??????
??????
????@Override??
????protected?void?onCreate(Bundle?savedInstanceState)?{??
????????//?TODO?Auto-generated?method?stub??
????????super.onCreate(savedInstanceState);??
????????myTabhost?=?this.getTabHost();??
????????//?get?Tabhost??
????????LayoutInflater.from(this).inflate(R.layout.main,??
????????????????myTabhost.getTabContentView(),?true);??
????????myTabhost.setBackgroundColor(Color.argb(150,?22,?70,?150));??
??
????????myTabhost.addTab(myTabhost.newTabSpec("One")//?make?a?new?Tab??
????????????????.setIndicator("查詢信息",?getResources().getDrawable(R.drawable.gimp))??
????????????????//?set?the?Title?and?Icon??
????????????????.setContent(R.id.widget_layout_Blue));??
????????//?set?the?layout??
??
????????myTabhost.addTab(myTabhost??
????????????????.newTabSpec("Two")??
????????????????//?make?a?new?Tab??
????????????????.setIndicator("簽到",??
????????????????????????getResources().getDrawable(R.drawable.mumule))??
????????????????//?set?the?Title?and?Icon??
????????????????.setContent(R.id.widget_layout_green));??
??
????}??
??
??????
??
????@Override??
????public?void?onTabChanged(String?tagString)?{??
????????//?TODO?Auto-generated?method?stub??
??????????
??????????
????}??
??
}??

下面我就如何 改變Tab標簽大小及間距作出說明：

我在網上查閱文檔，如果要改變此大小或者間距，必須將標簽欄寬高設為 wrapContent（其他的我尚未驗證）：以下為修改代碼及其效果：

?

?

import?android.app.TabActivity;??
import?android.graphics.Color;??
import?android.os.Bundle;??
import?android.view.LayoutInflater;??
import?android.view.View;??
import?android.view.ViewGroup.LayoutParams;??
import?android.widget.LinearLayout;??
import?android.widget.TabHost;??
import?android.widget.TabWidget;??
import?android.widget.TabHost.OnTabChangeListener;??
??
public?class?MyTab?extends?TabActivity?implements?OnTabChangeListener?{??
??
????private?TabHost?myTabhost;??
??????
??????
????@Override??
????protected?void?onCreate(Bundle?savedInstanceState)?{??
????????//?TODO?Auto-generated?method?stub??
????????super.onCreate(savedInstanceState);??
????????myTabhost?=?this.getTabHost();??
????????//?get?Tabhost??
????????LayoutInflater.from(this).inflate(R.layout.main,??
????????????????myTabhost.getTabContentView(),?true);??
????????myTabhost.setBackgroundColor(Color.argb(150,?22,?70,?150));??
??
????????myTabhost.addTab(myTabhost.newTabSpec("One")//?make?a?new?Tab??
????????????????.setIndicator("查詢信息",?getResources().getDrawable(R.drawable.gimp))??
????????????????//?set?the?Title?and?Icon??
????????????????.setContent(R.id.widget_layout_Blue));??
????????//?set?the?layout??
??
????????myTabhost.addTab(myTabhost??
????????????????.newTabSpec("Two")??
????????????????//?make?a?new?Tab??
????????????????.setIndicator("簽到",??
????????????????????????getResources().getDrawable(R.drawable.mumule))??
????????????????//?set?the?Title?and?Icon??
????????????????.setContent(R.id.widget_layout_green));??
??
????????//?首先得到標簽欄??
????????TabWidget?tabWidget?=?myTabhost.getTabWidget();??
????????//設置標簽欄寬高為?WRAP_CONTENT??
????????LinearLayout.LayoutParams?params?=?new?LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,?LayoutParams.WRAP_CONTENT);??
????????tabWidget.setLayoutParams(params);??
????????int?count?=?tabWidget.getChildCount();??
????????//得到每一個標簽，并設置其寬高??
?????????for?(int?i?=?0;?i?<?count;?i++)?{??
???????????????View?view?=?tabWidget.getChildTabViewAt(i);?????
???????????????view.getLayoutParams().height?=?50;?//tabWidget.getChildAt(i)??
???????????????view.getLayoutParams().width?=?80;??
??????????????}??
??
????}??
??
??????
??
????@Override??
????public?void?onTabChanged(String?tagString)?{??
????????//?TODO?Auto-generated?method?stub??
??????????
??????????
????}??
??
}??
