问题描述
我试图做一个ListView当我调用该函数actualizarDisplay它可以刷新（）。
我见过在日志猫的消息，我有abaout该消息的疑惑：
I'm trying to do a ListView that it can refresh when i call the function actualizarDisplay(). I've seen in the log cat a message, and i have doubts abaout that message:
10-06 12:24:02.524: I/dalvikvm(6911): Could not find method android.content.res.TypedArray.getType, referenced from method android.support.v7.internal.widget.TintTypedArray.getType

10-06 12:24:03.055: D/AbsListView(6911): unregisterIRListener() is called
我的问题是，当我按下屏幕onClickListener不reviced事件。
my problem is when i push the screen the event onClickListener is not reviced.
这是我的主要活动：
public class Rescate extends ActionBarActivity {
ArrayList<Ficha> listaFichas = new ArrayList<Ficha>();
MyCustomAdapter dataAdapter = null;
Ficha fichaAux = new Ficha();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rescate);
Bundle b = this.getIntent().getExtras();
int tipo=b.getInt("lugar");
switch(tipo) {
case 1:
break;
case 2:
break;
case 3:
break;
case 4:
fichaAux.setNumInv("1");
fichaAux.setIden("cuadro");
fichaAux.setUbi("sacrsitía");
fichaAux.setNumHom(2);
fichaAux.setMat("Plástico");
fichaAux.setEstado(0);
fichaAux.setPrioridad(1);
listaFichas.add(fichaAux);
fichaAux = new Ficha();
fichaAux.setNumInv("2");
fichaAux.setIden("cuadro");
fichaAux.setUbi("sacrsitía");
fichaAux.setNumHom(2);
fichaAux.setMat("Plástico");
fichaAux.setEstado(0);
fichaAux.setPrioridad(2);
listaFichas.add(fichaAux);
actualizarDisplay();
break;
default:
setContentView(R.layout.activity_rescate);
}
}
这是我的函数actualizarDisplay它实现了lsiteners：
this is my function actualizarDisplay which implements the lsiteners:
public void actualizarDisplay()
{
dataAdapter = new MyCustomAdapter(this,R.layout.listadofichas, listaFichas);
ListView listView = (ListView) findViewById(R.id.listaObras);
listView.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3)
{
Intent passIntent = new Intent();
passIntent.setClass(Rescate.this, VistaFicha.class);
Bundle bundle = new Bundle();
bundle.putCharSequence("num",listaFichas.get(arg2).getNumInv() );
bundle.putCharSequence("ubicacion",listaFichas.get(arg2).getUbi() );
passIntent.putExtras(bundle);
startActivity(passIntent);
}
});
listView.setOnItemLongClickListener(new OnItemLongClickListener()
{
public boolean onItemLongClick(AdapterView<?> arg0, View arg1, final int arg2, long arg3)
{
final String[] opciones = new String[] { "Si", "No"};
final AlertDialog.Builder dialogo = new AlertDialog.Builder(Rescate.this);
dialogo.setCancelable(true);
dialogo.setTitle("¿Desea establecer que la obra ha sido rescatada?");
dialogo.setItems(opciones, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
if (item == 0)
{
listaFichas.get(arg2).setEstado(1);
actualizarDisplay();
}
else
{
listaFichas.get(arg2).setEstado(0);
actualizarDisplay();
}
}
});
dialogo.setCancelable(false);
dialogo.create();
dialogo.show();
return false;
}
});
listView.setAdapter(dataAdapter);
}
这是我的函数来处理ListView的：
and this are my functions to handle the ListView:
public class FichaAdapter extends BaseAdapter
{
private ArrayList<Ficha> fichas;
public FichaAdapter(ArrayList<Ficha> fichas)
{
this.fichas = fichas;
//Cada vez que cambiamos los elementos debemos noficarlo
notifyDataSetChanged();
}
public int getCount()
{
return fichas.size();
}
public Object getItem(int position)
{
return fichas.get(position);
}
public long getItemId(int position)
{
return 0;
}
public View getView(int position, View convertView, ViewGroup parent)
{
FichaView view;
if (convertView == null) //NO existe, creamos uno
view = new FichaView(parent.getContext());
else //Existe, reutilizamos
view = (FichaView) convertView;
view.setFicha(fichas.get(position));
return view;
}
}
private class MyCustomAdapter extends ArrayAdapter<Ficha>
{
private ArrayList<Ficha> fichaList;
public MyCustomAdapter(Context context, int textViewResourceId,ArrayList<Ficha> fichaList)
{
super(context, textViewResourceId,fichaList);
this.fichaList = new ArrayList<Ficha>();
this.fichaList.addAll(fichaList);
}
private class ViewHolder
{
TextView num,iden,ubi,hombres,material;
ImageView foto;
RelativeLayout fondo;
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
ViewHolder holder = null;
if (convertView == null)
{
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.listadofichas, null);
holder = new ViewHolder();
holder.num = (TextView) convertView.findViewById(R.id.numInvResCon);
holder.iden = (TextView) convertView.findViewById(R.id.idenRescCont);
holder.ubi = (TextView) convertView.findViewById(R.id.ubiResCon);
holder.hombres = (TextView) convertView.findViewById(R.id.numHomResCon);
holder.material = (TextView) convertView.findViewById(R.id.matRescCon);
holder.foto = (ImageView) convertView.findViewById(R.id.imaResc);
holder.fondo = (RelativeLayout) convertView.findViewById(R.id.fondoRes);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
Ficha ficha = fichaList.get(position);
holder.num.setText(ficha.getNumInv());
holder.iden.setText(ficha.getIden());
holder.ubi.setText(ficha.getUbi());
holder.hombres.setText(String.valueOf(ficha.getNumHom()));
holder.material.setText(ficha.getMat());
if(ficha.getPrioridad()==1)
{
holder.num.setTextColor(Color.RED);
holder.iden.setTextColor(Color.RED);
holder.ubi.setTextColor(Color.RED);
holder.hombres.setTextColor(Color.RED);
holder.material.setTextColor(Color.RED);
}
if(ficha.getPrioridad()==2)
{
holder.num.setTextColor(Color.parseColor("#FF8000"));
holder.iden.setTextColor(Color.parseColor("#FF8000"));
holder.ubi.setTextColor(Color.parseColor("#FF8000"));
holder.hombres.setTextColor(Color.parseColor("#FF8000"));
holder.material.setTextColor(Color.parseColor("#FF8000"));
}
if(ficha.getPrioridad()==3)
{
holder.num.setTextColor(Color.GREEN);
holder.iden.setTextColor(Color.GREEN);
holder.ubi.setTextColor(Color.GREEN);
holder.hombres.setTextColor(Color.GREEN);
holder.material.setTextColor(Color.GREEN);
}
if(ficha.getEstado()== 1)
{
holder.fondo.setBackgroundColor(Color.GREEN);
holder.num.setTextColor(Color.WHITE);
holder.iden.setTextColor(Color.WHITE);
holder.ubi.setTextColor(Color.WHITE);
holder.hombres.setTextColor(Color.WHITE);
holder.material.setTextColor(Color.WHITE);
}
return convertView;
}
}
我觉得prgoblem是当日志猫说的知名度：0
我在这行的警告：
I think the prgoblem is when the log cat says visibility: 0 I have a warning in this line:
convertView = vi.inflate(R.layout.listadofichas, null);
我认为这个问题是在这里。
i think that the problem is here.
我写的布局：

该adpater效果很好，因为我可以改变颜色，..但听者不工作
谁能帮我？
The adpater works well because i can change the color,.. but the listener doesn't work Can anyone help me?
推荐答案
因此，这里是我的code。与字符串列表中的项目，而不是那些。数据表。我做了'Rescate.java第一延长 AppCompatActivity 然后 ActionBarActivity ，和它的工作了两个版本：
So here's my code with String list items instead of Ficha ones. I made 'Rescate.java' first extend AppCompatActivity and then ActionBarActivity, and it worked for both versions:
public class Rescate extends ActionBarActivity
{
ArrayList<String> listaFichas = new ArrayList<>();
MyCustomAdapter dataAdapter = null;
String fichaAux = "Hello";
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// setting this up with Strings to keep things simple
listaFichas.add("Hello");
listaFichas.add("Hi there");
actualizarDisplay();
}
public void actualizarDisplay()
{
dataAdapter = new MyCustomAdapter(this,R.layout.listadofichas, listaFichas);
ListView listView = (ListView) findViewById(R.id.listaObras);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3)
{
Intent passIntent = new Intent();
passIntent.setClass(Rescate.this, VistaFicha.class);
startActivity(passIntent);
}
});
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener()
{
public boolean onItemLongClick(AdapterView<?> arg0, View arg1, final int arg2, long arg3)
{
final String[] opciones = new String[]{"Si", "No"};
final AlertDialog.Builder dialogo = new AlertDialog.Builder(Rescate.this);
dialogo.setCancelable(true);
dialogo.setTitle("¿Desea establecer que la obra ha sido rescatada?");
dialogo.setItems(opciones, new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int item)
{
if (item == 0)
{
actualizarDisplay();
Toast.makeText(Rescate.this, "item = 0", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(Rescate.this, "item != 0", Toast.LENGTH_SHORT).show();
}
}
});
dialogo.setCancelable(false);
dialogo.create();
dialogo.show();
return false;
}
});
listView.setAdapter(dataAdapter);
}
}
VistaFicha.java'只是显示Hello World的一个空白的活动。
'VistaFicha.java' is just a blank activity showing "Hello World".
我把adpater在一个单独的文件'MyCustomAdapter.java
I put the adpater in a separate file 'MyCustomAdapter.java'
public class MyCustomAdapter extends ArrayAdapter
{
private ArrayList<String> fichaList;
private LayoutInflater vi;
public MyCustomAdapter(Context context, int textViewResourceId,ArrayList<String> fichaList)
{
super(context, textViewResourceId,fichaList);
this.fichaList = new ArrayList<String>();
this.fichaList.addAll(fichaList);
// I had to change the original code because my adapter is not an inner class:
vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
private class ViewHolder
{
TextView num;
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
ViewHolder holder = null;
if (convertView == null)
{
convertView = vi.inflate(R.layout.listadofichas, null);
holder = new ViewHolder();
holder.num = (TextView) convertView.findViewById(R.id.tvHallo);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
String ficha = fichaList.get(position);
holder.num.setText(ficha);
return convertView;
}
}
有关列表的行XML是一个简单的的TextView （R.id.tvHallo）内的的LinearLayout 和我收复活动包含只有平时的Hello World和的ListView （R.id.listaObras）
The xml for the list rows is simply a TextView (R.id.tvHallo) inside a LinearLayout and my Rescate activity contains only the usual "Hello World" and the ListView (R.id.listaObras)
希望这会有所帮助，让我知道，如果有任何问题：）
Hope this helps, and let me know if there are any questions :)
