最终效果图如下：(选图有点丑emmm)

本次实验主要涉及了：

1.标签设置时文字和图片不能同时显示问题

解决方法：修改AndroidManifest.xml里的 android:theme变成android:theme="@android:style/Theme.Black"

另外，网上也有说可以自定义View，暂时没试

2.由于白色的标签文字看不清楚，于是想到改变字的颜色，参考https://www.cnblogs.com/yuxuan007/p/7238980.html

最终MainActivity.java代码如下：

private TabHost tabhost;

TextView tv;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

tabhost = getTabHost();

tv=(TextView)findViewById(R.id.sj);

//View tabIndicator = LayoutInflater.from(this).inflate(R.layout.activity_receive_top, getTabWidget(), false);

//增加选项卡名

Intent ReceiveIntent = new Intent(MainActivity.this,ReceiveActivity.class);

tabhost.addTab(tabhost.newTabSpec("tag1").setIndicator("收件箱",getResources().getDrawable(R.drawable.ic_tab_receive)).setContent(ReceiveIntent));

Intent SendIntent = new Intent(MainActivity.this,SendActivity.class);

tabhost.addTab(tabhost.newTabSpec("tag2").setIndicator("发件箱",getResources().getDrawable(R.drawable.ic_tab_send)).setContent(SendIntent));

Intent DeletedIntent = new Intent(MainActivity.this,DeletedActivity.class);

tabhost.addTab(tabhost.newTabSpec("tag3").setIndicator("已删除",getResources().getDrawable(R.drawable.ic_tab_deleted)).setContent(DeletedIntent));

tabhost.setCurrentTabByTag("tag1");

//选项卡切换事件处理

tabhost.setOnTabChangedListener(new TabHost.OnTabChangeListener() {

@Override

public void onTabChanged(String tabId) {

upDateTab(tabhost);

Toast.makeText(MainActivity.this,"当前选中："+tabId+"标签",Toast.LENGTH_SHORT).show();

}

});

}

/**

* 更新文字颜色。

*

* @param mTabHost

*/

private void upDateTab(TabHost mTabHost) {

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

TextView tv = (TextView) mTabHost.getTabWidget().getChildAt(i).findViewById(android.R.id.title);

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

tv.setTextColor(this.getResources().getColor(R.color.colorAccent));

} else {//不选中

tv.setTextColor(this.getResources().getColor(R.color.colorPrimary));

}

}

}

好啦，结束了！
