我想我变得疯了.如此简单的东西将自定义适配器绑定到Listview让我头疼.

发布代码然后解释:

MainActivity.java

package com.example.pruebalist;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivity extends Activity {

    private static String[] data = new String[] {"0","1","2","3"};

    public void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        Log.v("MainActivity","Inside MainActivity");
        setContentView(R.layout.main);
        ListView lstView = (ListView)findViewById(R.id.listNoticias);

        ArrayAdapter<String> adapter = new LstAdapter(this, R.layout.row, data);
        lstView.setAdapter(adapter);
    }

}

LstAdapter.java

package com.example.pruebalist;

import android.app.Activity;
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

public class LstAdapter extends …

我在Android教程中执行了一些DatePickerDialog问题.

在获得焦点时链接TextView以启动DatePickerDialog,如下所示:

EditText fNac = (EditText)findViewById(R.id.regFecha);
            fNac.setonfocusChangeListener(new View.onfocusChangeListener(){

                    @Override
                    public void onfocusChange(View v, boolean hasFocus) {
                            // TODO Auto-generated method stub
                            // Desde aquí lanzamos el datepicker
                            if (hasFocus){
                                    DialogFragment newFragment = new DatePickerFragment();
                                    newFragment.show(getSupportFragmentManager() , "datePicker");
                            }
                    }

工作正常,DatePickerDialog启动.我实例化了一个以这种方式创建的新DatePickerFragment类:

import java.util.Calendar;

import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.util.Log;
import android.widget.DatePicker;

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

    private DatePickerDialog mDatePickerDialog;

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState){
            // Usamos la fecha actual como primera fecha a mostrar …
