Android开发之自己定义TabHost文字及背景(源码分享)

使用TabHost 能够在一个屏幕间进行不同版面的切换，而系统自带的tabhost界面较为朴素，我们应该怎样进行自己定义改动优化呢

MainActivity的源码

package com.dream.ledong;

import android.app.TabActivity;

import android.content.Intent;

import android.graphics.Color;

import android.os.Bundle;
import android.view.Gravity;

import android.widget.RelativeLayout;

import android.widget.TabHost;

import android.widget.TabHost.OnTabChangeListener;

import android.widget.TabWidget;

import android.widget.TextView;
import com.example.client.R;
@SuppressWarnings("deprecation")

public class itemList extends TabActivity {

	@Override

	public void onCreate(Bundle savedInstanceState) {

		// TODO Auto-generated method stub

		super.onCreate(savedInstanceState);

		setContentView(R.layout.itemlist);

		final TabHost tabHost = getTabHost();

		Intent remoteIntent = new Intent(itemList.this, item1.class);

		TabHost.TabSpec remoteTabSpec = tabHost.newTabSpec("remote");

		remoteTabSpec.setIndicator("运动推荐");

		remoteTabSpec.setContent(remoteIntent);

		tabHost.addTab(remoteTabSpec);
Intent localIntent = new Intent(itemList.this, item2.class);

		TabHost.TabSpec localTabSpec = tabHost.newTabSpec("local");

		localTabSpec.setIndicator("球友人气");

		localTabSpec.setContent(localIntent);

		tabHost.addTab(localTabSpec);
Intent localIntent2 = new Intent(itemList.this, item2.class);

		TabHost.TabSpec localTabSpec2 = tabHost.newTabSpec("a");

		localTabSpec2.setIndicator("竞技氛围");

		localTabSpec2.setContent(localIntent2);

		tabHost.addTab(localTabSpec2);
updateTabStyle(tabHost);
// 当某个Tab被选中时，则更新背景样式

		tabHost.setOnTabChangedListener(new OnTabChangeListener() {

			@Override

			public void onTabChanged(String tabId) {

				updateTabStyle(tabHost);

			}

		});

	}
private void updateTabStyle(final TabHost mTabHost) {

		TabWidget tabWidget = mTabHost.getTabWidget();

		tabWidget.setRightStripDrawable(R.drawable.list_item_divide_operate);

		tabWidget.setLeftStripDrawable(R.drawable.list_item_divide_operate);

		for (int i = 0; i < tabWidget.getChildCount(); i++) {

			RelativeLayout tabView = (RelativeLayout) mTabHost.getTabWidget()

					.getChildAt(i);

			TextView text = (TextView) tabWidget.getChildAt(i).findViewById(

					android.R.id.title);

			text.setTextSize(15);

			RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) text

					.getLayoutParams();

			params.width = RelativeLayout.LayoutParams.MATCH_PARENT;

			params.height = RelativeLayout.LayoutParams.MATCH_PARENT;

			text.setLayoutParams(params);

			text.setGravity(Gravity.CENTER);

			if (mTabHost.getCurrentTab() == i) {

				// 选中

				tabView.setBackgroundColor(Color.parseColor("#8DB6CD"));

				text.setTextColor(this.getResources().getColorStateList(

						android.R.color.black));

			} else {

				// 未选中

				tabView.setBackgroundColor(Color.parseColor("#ffffff"));

				text.setTextColor(this.getResources().getColorStateList(

						android.R.color.darker_gray));

			}

		}

	}
}
