你好,我正在开发一款针对教育领域的Android启动器。我需要在用户点击学校工具按钮时,启动已安装在设备上的学校工具应用程序。
以下是代码:
package com.d4a.stzh;
import android.net.Uri;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.content.Intent;
import com.actionbarsherlock.app.SherlockFragment;
public class FragmentTab1 extends SherlockFragment {
private Button appbtn;
private Button webbtn;
private Button toolsbttn;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Get the view from fragmenttab1.xml
View view = inflater.inflate(R.layout.fragmenttab1, container, false);
//Get the button from layout
appbtn = (Button) view.findViewById(R.id.app);
webbtn = (Button) view.findViewById(R.id.web);
toolsbttn = (Button) view.findViewById(R.id.tools);
//show all apps installed on the device
appbtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(FragmentTab1.this.getActivity(), MyLauncherActivity.class);
startActivity(intent);
}
});
//luanches google on the default web browser
webbtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
String url = "http://www.google.com";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
});
//tools button i know ths code is wrong!I need help here!
toolsbttn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(FragmentTab1.this.getActivity(), MyLauncherActivity.class);
startActivity(intent);
}
});
return view;
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
setUserVisibleHint(true);
}
}
我对安卓编程还很陌生,所以请不要评判我。
任何帮助都将不胜感激。非常感谢提前的帮助!
祝好!
