Question

我正在尝试创建一个简单的程序，当它运行时显示一个按钮，当用户单击该按钮时，它们将被带到一个网页。但是，我一直收到“找不到处理意图的活动”错误。这是我目前的清单文件中的内容：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="school.project.application"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="10" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="school.project.application.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity   
        android:name=".AppPreferenceActivity" 
        android:label="@string/app_name">  
        <intent-filter> 
             <action android:name="android.Intent.ACTION_VIEW" />  

             <category android:name="android.intent.category.DEFAULT" />  
        </intent-filter>   
    </activity>
</application>
</manifest>

这是我在点击按钮时用来启动网页的代码： package school.project.application;

import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import android.content.Intent;
import android.os.Bundle;
import android.net.Uri;


public class MainActivity extends Activity {
private final String TAG = "sendButton";
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    setupsendMessage();



}


private void setupsendMessage() {
// do something when the button is pressed
//
Button sendButton = (Button) findViewById(R.id.button1);

sendButton.setOnClickListener(new View.OnClickListener(){

    @Override
    public void onClick(View v) {
        Log.i(TAG, "You Clicked a button");
        goToUrl("htpp://stackoverflow.com/");


        }
    });
}


@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;
}

public void goToSo (View view){
    goToUrl("http://stackoverflow.com/");

}
private void goToUrl(String url){
    Uri uriUrl = Uri.parse(url);
    Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);
    startActivity(launchBrowser);
}

}

我想知道是否有人可以花一些时间来帮我纠正这个问题？非常感谢你们。

Answer 1

您的网址似乎有拼写错误： goTo Url（“http://stackoverflow.com/”）;

应该是：

goToUrl（ “https://stackoverflow.com/”）;

没有找到活动来处理Intent，找不到解决方案android应用程序
