tabhost的问题?
不使用tabActivity改用Activity出错了?求解?调试执行到tabHost.addTab(tabSpec1);
错误信息:
Source not found.
求解?
源码如下:
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.widget.RadioGroup;
import android.widget.TabHost;
public class MainActivity extends Activity{
private RadioGroup group;
private TabHost tabHost;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mytabhost);
tabHost = (TabHost) findViewById(R.id.mytabhost1);
tabHost.setup();
TabHost.TabSpec tabSpec1 = (TabHost.TabSpec)tabHost.newTabSpec("home").setIndicator("home");
tabSpec1.setContent(new Intent(MainActivity.this,webView.class));
tabHost.addTab(tabSpec1);
}
}
webView.class代码
public class webView extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
WebView webView=(WebView)findViewById(R.id.webView);
String strUrl="http://www.126.com";
webView.loadUrl(strUrl);
}
}
xml布局代码
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mytabhost1"
android:layout_width="match_parent"
