我有一个listview作为左边的文本和右边的复选框。我的列表视图显示带有短信主体和地址的收件箱。当我点击复选框并使用它保存时,我想要获取地址button.my复选框是可点击的,我的列表视图无法点击,因为它显示为文本。 我的代码如下:

public class SMSInbox extends Activity{

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

        final ListView lViewSMS = (ListView) findViewById(R.id.list);  

        if(fetchInbox()!=null)  
        {  
            String[] from = new String[]{};

            int to = R.id.text1;
            ArrayAdapter adapter = new ArrayAdapter(this,R.layout.row,to,fetchInbox());  

            lViewSMS.setAdapter(adapter);  
        }


        }    


    public ArrayList fetchInbox()  
    {  
        ArrayList sms = new ArrayList();  

        Uri uriSms = Uri.parse("content://sms/inbox");  
        Cursor cursor = getContentResolver().query(uriSms, new String[]{"_id", "address", "date", "body"},null,null,null);   

        cursor.moveToFirst();  
        while  (cursor.moveToNext())  
        {  
               String address = cursor.getString(1);  
               String body = cursor.getString(3);  

               System.out.println("======> Mobile number => "+address);  
               System.out.println("=====> SMS Text => "+body);  

               sms.add("Address=> "+address+"\n SMS => "+body);  
        }  
        return sms;  

    }


        }

我的XML代码inbox.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" >
<Button android:id="@+id/get_view_button" 
android:layout_width="wrap_content"
android:layout_height="wrap_content" 
android:text="Get CheckBox" />
<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>

我的row.xml代码:

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

<TextView
android:id="@+id/text1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dip">
</TextView>

<CheckBox
android:id="@+id/check"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginLeft="4px"
android:layout_marginRight="10px" >
</CheckBox>

</RelativeLayout>

查看代码:

    public class InteractiveArrayAdapter extends ArrayAdapter<Model> {

private final List<Model> list;
private final Activity context;

public InteractiveArrayAdapter(Activity context, List<Model> list) {
    super(context, R.layout.row, list);
    this.context = context;
    this.list = list;
}

static class ViewHolder {
    protected TextView text;
    protected CheckBox checkbox;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view = null;
    if (convertView == null) {
        LayoutInflater inflator = context.getLayoutInflater();
        view = inflator.inflate(R.layout.row, null);
        final ViewHolder viewHolder = new ViewHolder();
        viewHolder.text = (TextView) view.findViewById(R.id.text1);
        viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);
        viewHolder.checkbox
                .setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

                    @Override
                    public void onCheckedChanged(CompoundButton buttonView,
                            boolean isChecked) {
                        Model element = (Model) viewHolder.checkbox
                                .getTag();
                        element.setSelected(buttonView.isChecked());



                    }
                });
        view.setTag(viewHolder);
        viewHolder.checkbox.setTag(list.get(position));

    } else {
        view = convertView;
        ((ViewHolder) view.getTag()).checkbox.setTag(list.get(position));

    }
    ViewHolder holder = (ViewHolder) view.getTag();
    holder.text.setText(list.get(position).getName());
    holder.checkbox.setChecked(list.get(position).isSelected());
    return view;
}}

Model.java

    public class Model {
private String name;
private boolean selected;

public Model(String name) {
    this.name = name;
    selected = false;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public boolean isSelected() {
    return selected;
}

public void setSelected(boolean selected) {
    this.selected = selected;
}}

让我知道如何通过复选框点击从smsinbox.java获取地址。如何确认是复选框获取地址?

在适配器中添加此方法:

首先为所选项目列表定义新ArrayList

ArrayList<String> listChosen = new ArrayList<>();

创建一个返回列表的方法:

/**
     * create this method for return new value in list item selected
     * @return
     */
    private List<String> getSelectedString(){
        return itemSelected;
    }
在复选框条件中

,请执行以下代码:

 holder.cbItem.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                if(b){
                    itemSelected.add(itemName);

                    String jsonString = gson.toJson(getSelectedString());
                    edit.putString(Constants.KEY_SHARED,jsonString);
                    edit.commit();
                }else{
                    itemSelected.remove(itemName);
                    String jsonString = gson.toJson(getSelectedString());
                    edit.putString(Constants.KEY_SHARED,jsonString);
                    edit.commit();
                }
            }
        });
