Java 在android应用程序中使用neuroph源代码

我曾尝试使用java中的neuroph源代码创建一个android神经网络，但失败了。 源链接，在页面末尾： 图书馆地址：

我的活动课：

public class TestNeuroph extends Activity {
    MyAdapter adapter;
    ListView listview;
    List<Row> Rows = new ArrayList<Row>();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test_neuroph);

        adapter = new MyAdapter(this);
        listview = (ListView)findViewById(R.id.listView1);

        Button btnProccess = (Button) findViewById(R.id.buttonProccess);
        btnProccess.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                 // create training set (logical XOR function)
                DataSet trainingSet = new DataSet(2, 1);
                trainingSet.addRow(new DataSetRow(new double[]{0, 0}, new double[]{0}));
                trainingSet.addRow(new DataSetRow(new double[]{0, 1}, new double[]{1}));
                trainingSet.addRow(new DataSetRow(new double[]{1, 0}, new double[]{1}));
                trainingSet.addRow(new DataSetRow(new double[]{1, 1}, new double[]{0}));
                // create multi layer perceptron
                MultiLayerPerceptron myMlPerceptron = new MultiLayerPerceptron(TransferFunctionType.TANH, 2, 3, 1);
                // learn the training set
                myMlPerceptron.learn(trainingSet);
                // test perceptron
                //Toast.makeText(getBaseContext(), "Testing trained neural network", Toast.LENGTH_LONG).show();
                testNeuralNetwork(myMlPerceptron, trainingSet);
                Log.d("Add_Food", "save trained neural network");
                // save trained neural network
                myMlPerceptron.save("myMlPerceptron.nnet");
                // load saved neural network
                NeuralNetwork loadedMlPerceptron = NeuralNetwork.createFromFile("myMlPerceptron.nnet");
                // test loaded neural network
                //Toast.makeText(getBaseContext(), "Testing loaded neural network", Toast.LENGTH_LONG).show();
                testNeuralNetwork(loadedMlPerceptron, trainingSet);

                adapter.setData(Rows);
                listview.setAdapter(adapter);
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_test_neuroph, menu);
        return true;
    }

     public  void testNeuralNetwork(NeuralNetwork nnet, DataSet testSet) {

            for(DataSetRow dataRow : testSet.getRows()) {
                nnet.setInput(dataRow.getInput());
                nnet.calculate();
                double[ ] networkOutput = nnet.getOutput();
                Row r = new Row();
                r.setInput(Arrays.toString(dataRow.getInput()));
                r.setOutput(Arrays.toString(networkOutput));
                Rows.add(r);
            }
        }
}

my row.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView" />

</LinearLayout>

有人能帮我吗

向您致意。

有吗？我将所有库逐一添加到我的android项目中

NoClassDefFoundError

表示运行时找不到库。这可能意味着您需要设置类路径。请参阅我在上面发布的链接。
