在这里,我制作了5个工作正常的Tab按钮,但现在我想为每个Tab添加图标,如何相对于Tab按钮添加Tab图标….请指导/帮助我.

我第一次使用stackOverflow,请告诉我在发布此代码时是否错过了任何步骤…

提前致谢

package com.vishesh.soapbox;

import android.app.TabActivity;

import android.content.Context;

import android.content.Intent;

import android.content.res.Resources;

import android.os.Bundle;

import android.view.LayoutInflater;

import android.view.View;

import android.widget.Button;

import android.widget.TabHost;

import android.widget.TextView;

import android.widget.TabHost.TabSpec;

public class Start extends TabActivity {

private TabHost tabHost;

//Resources res=getResources();

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.start);

//textView for signout from application

TextView signout=(TextView)findViewById(R.id.signout);

signout.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

finish();

}

});

// scan button use for read the BarCode through RedLaser

Button scan=(Button)findViewById(R.id.scan);

final Intent intent=new Intent(this,RLSample.class);

scan.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

startActivity(intent);

}

});

//for Tab button

tabHost=getTabHost();

setupTabhost();

Intent intent1=new Intent().setClass(this, SoapBox.class);

setupTab(new TextView(this),"SoapBox", intent1);

Intent intent2=new Intent().setClass(this, Profile.class);

setupTab(new TextView(this),"Profile", intent2);

Intent intent3=new Intent().setClass(this, Challenges.class);

setupTab(new TextView(this),"Challenges", intent3);

Intent intent4=new Intent().setClass(this, Vault.class);

setupTab(new TextView(this),"Vault", intent4);

Intent intent5=new Intent().setClass(this, More.class);

setupTab(new TextView(this),"More", intent5);

tabHost.setCurrentTab(0);

}

private void setupTabhost()

{

tabHost=(TabHost)findViewById(android.R.id.tabhost);

tabHost.setup();

}

private void setupTab(final View view, final String tag, Intent intent)

{

View tabView=createTabView(tabHost.getContext(),tag);

TabSpec tabSpec=tabHost.newTabSpec(tag).setIndicator(tabView).setContent(intent);

tabHost.addTab(tabSpec);

}

private static View createTabView(final Context context, final String text)

{

View view=LayoutInflater.from(context).inflate(R.layout.start_tabs_bg, null);

TextView textView=(TextView)view.findViewById(R.id.tabsText);

textView.setText(text);

return view;

}

}

解决方法:

Vishesh,

如果看示例HERE …

spec = tabHost.newTabSpec("albums").setIndicator("Albums",

res.getDrawable(R.drawable.ic_tab_albums))

.setContent(intent);

可绘制图标在对setIndicator()的调用中传递.您也可以用tag变量替换两个“专辑”字符串.

虽然,目前看来您正在为标签使用自定义视图.您只需要向布局添加一个ImageView并将可绘制对象设置为所需的图标即可.
