java - 包含 GaugeView 库后的 Android ClassNotFoundException

Question

我正在尝试使用 github 中的仪 TableView
随库提供的示例应用程序运行完美!

但是当我尝试将库包含到项目中(属性>构建路径>项目>(添加库项目))时，将 View 放入我的布局中并尝试在它抛出的代码中获取对 View 的引用类NotFoundException

以下是我通过 logcat 得到的错误:

W/ActivityManager(   77):   Force finishing activity com.example.guagetest/.MainActivity

我不知道为什么找不到该类(class)。请有人帮忙。示例应用程序中是否需要执行任何特殊操作才能使其正常工作？

以下是我的布局:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <org.codeandmagic.android.gauge.GaugeView
     android:id="@+id/gauge_view1"
     android:layout_width="match_parent"
     android:layout_height="0dp"
     android:layout_weight="1" />


</LinearLayout>

这是我的 Activity :

package com.example.guagetest;

import org.codeandmagic.android.gauge.GaugeView;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

    private GaugeView gauge;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        gauge = (GaugeView) findViewById(R.id.gauge_view1);
        gauge.setTargetValue(10);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}

您没有发布任何代码，但即使在您的帖子中，您对特定单词的拼写也不一致，这一事实表明您需要检查代码中的拼写方式。仔细看这两个字:

String correct = "gauge";
String wrongWrongWrong = "guage";
