那位大虾，知道，android:TabHost,选项卡的，文字居中。270781058

给TAB卡做个布局，在布局里面把TextView设置成居中
给个事例给你看下
TabHost.TabSpec localTabSpec1 = this.tabHost.newTabSpec("1");
//R.Layout.tab_indicator 就是TAB选项卡的布局
View localView = getLayoutInflater().inflate(R.layout.tab_indicator, null);
ImageView localImageView = (ImageView) localView.findViewById(R.id.icon);
localImageView.setImageResource(R.drawable.menu_ranking);
TabHost.TabSpec localTabSpec2 = localTabSpec1.setIndicator(localView);
Intent localIntent = new Intent(this, RankActivity.class);
localTabSpec2.setContent(localIntent);
this.tabHost.addTab(localTabSpec1);

查查API文档看看

android:gravity="center"不行吗？
