我正在尝试掌握Java和Android,希望在单击按钮后打开用户浏览器的简单任务中获得帮助。
我已经做了两天的教程,但如果我自己尝试并得到反馈可能会更有帮助。提前感谢任何帮助。
main.xml:
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"

GetURL.java:
package com.patriotsar;
import android.app.Activity;
import android.content.Intent;
import android.view.View.OnClickListener;
String url = "http://www.yahoo.com";
Intent i = new Intent(Intent.ACTION_VIEW);
Uri u = Uri.parse(url);
i.setData(u);
public class patriosar extends Activity {
private Button goButton;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
goButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v){
try {
// Start the activity
startActivity(i);
} catch (ActivityNotFoundException e) {
// Raise on activity not found
Toast toast = Toast.makeText(context, "Browser not found.", Toast.LENGTH_SHORT);
}
}
});
}
}
