Android 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;


    @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("查询信息", 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("签到",
                        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;


    @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("查询信息", 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("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_CONTENT
        LinearLayout.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;
              }

    }



    @Override
    public void onTabChanged(String tagString) {
        // TODO Auto-generated method stub


    }

}
