Android speichern Kontrollkästchen Status in der ListView mit den Cursor-Adapter

Ich hatte das gleiche Problem mich: wie, um umzuschalten, wählen Sie mehrere CheckedTextView in einem benutzerdefinierten layout (ich.e nicht mit android.R.layout.simple_list_item_multiple_choice)

Folgende für mich gearbeitet. Das Beispiel, das ich habe, ist eine benutzerdefinierte Ansicht, die vorgesehen ist, einen Adapter erweitert, von SimpleCursorAdapter.

Meine benutzerdefinierte Ansicht (row_contact.xml):

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_height="wrap_content" android:layout_width="fill_parent">

  <CheckedTextView
    android:id="@android:id/text1"
    android:layout_width="fill_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:gravity="center_vertical"
    android:paddingLeft="6dip"
    android:paddingRight="6dip" 
    android:checkMark="?android:attr/listChoiceIndicatorMultiple"
    />

  <TextView
    android:text="@+id/TextView01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/tvNumber"
    android:layout_gravity="bottom" 
    android:paddingLeft="6dip"
    android:paddingRight="6dip" 
    />

</FrameLayout>

Den Adapter erstellt wird, in der ListActivity.OnCreate, die fordert, setupViews():

  private void setupViews() {
    bOk       = (Button) findViewById(R.id.ButtonOK);
    bCancel   = (Button) findViewById(R.id.ButtonCancel);
    FListView = getListView(); 
    //
    bOk.setText("Select");
    //
    FListView.setItemsCanFocus(false);
    FListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    //
    bOk.setOnClickListener(this);
    bCancel.setOnClickListener(this);
    //
    ContentResolver content = getContentResolver();
    Cursor cursor = ApplicationHelper.MobilePhoneContacts(content);
    startManagingCursor(cursor);

    ListAdapter adapter = new CheckedCursorAdapter( SelectContacts.this, R.layout.row_contact, cursor,                
        new String[] {People.NAME, People.NUMBER},               
        new int[] {android.R.id.text1, R.id.tvNumber});          
    setListAdapter(adapter);
  }

Den Benutzerdefinierten Adapter:

  public class CheckedCursorAdapter extends SimpleCursorAdapter {

    Activity context;
    Cursor c;

    public CheckedCursorAdapter(Activity context, int rowContact, Cursor cursor, String[] strings, int[] is) {
      super(context, rowContact, cursor, strings, is);
      this.context = context;
      this.c = cursor;

    }

    public View getView(int position, View convertView, ViewGroup parent) {
      View row = convertView;
      ContactRowWrapper wrapper;

      if (row == null) {
        LayoutInflater inflater=context.getLayoutInflater();
        row = inflater.inflate(R.layout.row_contact, null);
        //
        wrapper = new ContactRowWrapper(row);
        row.setTag(wrapper);
      } else {
        wrapper = (ContactRowWrapper)row.getTag();
      }
      c.moveToPosition(position);
      wrapper.getTextView().setText( c.getString(c.getColumnIndex(Contacts.People.NUMBER)) );
      wrapper.getcheckBox().setText( c.getString(c.getColumnIndex(Contacts.People.NAME)) );
      wrapper.getcheckBox().setChecked(getListView().isItemChecked(position));
      //
      return row;
    }

  }

Das entscheidende Stück code für mich war der check-Boxen arbeiten war:

wrapper.getcheckBox().setChecked(getListView().isItemChecked(position));

Hoffe das hilft dir oder sonst jemand, der stolpert auf diese Frage.

Außerdem, entschuldigen Sie meine Java-noobness... ich habe erst angefangen Java vor ein paar Wochen.

3. Code Code
Attach listeners inside your activity “onCreate()” method, to monitor following events :

If checkbox id : “chkIos” is checked, display a floating box with message “Bro, try Android”.
If button is is clicked, display a floating box and display the checkbox states.
File : MyAndroidAppActivity.java

package com.mkyong.android;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.Toast;

public class MyAndroidAppActivity extends Activity {

  private CheckBox chkIos, chkAndroid, chkWindows;
  private Button btnDisplay;

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    addListenerOnChkIos();
    addListenerOnButton();
  }

  public void addListenerOnChkIos() {

    chkIos = (CheckBox) findViewById(R.id.chkIos);

    chkIos.setOnClickListener(new OnClickListener() {

      @Override
      public void onClick(View v) {
                //is chkIos checked?
        if (((CheckBox) v).isChecked()) {
            Toast.makeText(MyAndroidAppActivity.this,
               "Bro, try Android :)", Toast.LENGTH_LONG).show();
        }

      }
    });

  }

  public void addListenerOnButton() {

    chkIos = (CheckBox) findViewById(R.id.chkIos);
    chkAndroid = (CheckBox) findViewById(R.id.chkAndroid);
    chkWindows = (CheckBox) findViewById(R.id.chkWindows);
    btnDisplay = (Button) findViewById(R.id.btnDisplay);

    btnDisplay.setOnClickListener(new OnClickListener() {

          //Run when button is clicked
      @Override
      public void onClick(View v) {

        StringBuffer result = new StringBuffer();
        result.append("IPhone check : ").append(chkIos.isChecked());
        result.append("\nAndroid check : ").append(chkAndroid.isChecked());
        result.append("\nWindows Mobile check :").append(chkWindows.isChecked());

        Toast.makeText(MyAndroidAppActivity.this, result.toString(),
                Toast.LENGTH_LONG).show();

      }
    });

  }
