Android(安卓)默认Tab标签大小及间距修改

一般来说，我都是用Android默认的Tab，但此时Android会根据你增加的Tab页面平均分配Tab标签，假如你只有两个Tab，那么长度将会很长，并且其高度略微过高，并不好看，网上解决这个问题有些是自定义Tab。我们仍然使用默认的Tab解决此问题。

修改前代码、图片如下：

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;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);myTabhost = this.getTabHost();// get TabhostLayoutInflater.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("查询信息", getResources().getDrawable(R.drawable.gimp))// set the Title and Icon.setContent(R.id.widget_layout_Blue));// set the layoutmyTabhost.addTab(myTabhost.newTabSpec("Two")// make a new Tab.setIndicator("签到",getResources().getDrawable(R.drawable.mumule))// set the Title and Icon.setContent(R.id.widget_layout_green));}@Overridepublic void onTabChanged(String tagString) {// TODO Auto-generated method stub}}

下面我就如何改变Tab标签大小及间距作出说明：

我在网上查阅文档，如果要改变此大小或者间距，必须将标签栏宽高设为 wrapContent（其他的我尚未验证）：以下为修改代码及其效果：

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;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);myTabhost = this.getTabHost();// get TabhostLayoutInflater.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("查询信息", getResources().getDrawable(R.drawable.gimp))// set the Title and Icon.setContent(R.id.widget_layout_Blue));// set the layoutmyTabhost.addTab(myTabhost.newTabSpec("Two")// make a new Tab.setIndicator("签到",getResources().getDrawable(R.drawable.mumule))// set the Title and Icon.setContent(R.id.widget_layout_green));// 首先得到标签栏TabWidget tabWidget = myTabhost.getTabWidget();//设置标签栏宽高为 WRAP_CONTENTLinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);tabWidget.setLayoutParams(params);int count = tabWidget.getChildCount();//得到每一个标签，并设置其宽高 for (int i = 0; i < count; i++) {   View view = tabWidget.getChildTabViewAt(i);      view.getLayoutParams().height = 50; //tabWidget.getChildAt(i)   view.getLayoutParams().width = 80;  }}@Overridepublic void onTabChanged(String tagString) {// TODO Auto-generated method stub}}
