次のコードは例から取得しましたが、アプリは常にクラッシュします。
package com.example.tabview;
import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
import android.view.Menu;
@SuppressWarnings("deprecation")
public class MainActivity extends TabActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Resources ressources = getResources();
TabHost tabHost = getTabHost();
// Android tab
Intent intentAndroid = new Intent().setClass(this, AndroidActivity.class);
TabSpec tabSpecAndroid = tabHost
.newTabSpec("Android")
.setContent(intentAndroid);
// Apple tab
Intent intentApple = new Intent().setClass(this, AppleActivity.class);
TabSpec tabSpecApple = tabHost
.newTabSpec("Apple")
.setContent(intentApple);
// Windows tab
Intent intentWindows = new Intent().setClass(this, WindowsActivity.class);
TabSpec tabSpecWindows = tabHost
.newTabSpec("Windows")
.setContent(intentWindows);
// add all tabs
tabHost.addTab(tabSpecAndroid);
tabHost.addTab(tabSpecApple);
tabHost.addTab(tabSpecWindows);
//set Windows tab as default (zero based)
tabHost.setCurrentTab(2);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
