java - 如何知道 ListView 特定行的复选框值

Question

嘿，我怎么知道单击时下面的复选框来自列表的哪一行。有什么方法可以知道这一点吗？每次 yo 都会返回 false，这是它的默认值。

checkBox.setOnClickListener( new View.OnClickListener() {
                    public void onClick(View v) {
                        CheckBox cb = (CheckBox) v ;
                        callBlockOptions callBlockOptions = (callBlockOptions) cb.getTag();

                        callBlockOptions.setChecked( cb.isChecked() );

                        String yo;

                        if(callBlockOptions.getPosition()=="0")
                        {
                            callBlockOptions.setAllCalls();
                        }


                        if(callBlockOptions.getAllCalls() ==true)
                            yo="true";
                        else
                            yo="false";

                        Toast.makeText(getContext(), callBlockOptions.getPosition(), Toast.LENGTH_LONG).show();

                    }
                });        
            }

查看代码后，您可能想要尝试的一件事是为 ListView 中的各个子项设置监听器。你可以这样做:

ListView listView = (ListView)findViewById(R.id.listView);
int count = listView.getChildCount();
for (int x = 0; x < count; x++)
{
    Class<? extends View> c = listView.getChildAt(x).getClass();
    if (c == CheckBox.class)
    {
        CheckBox checkBox = (CheckBox)(listView.getChildAt(x));
        checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener(){

            @Override
            public void onCheckedChanged(CompoundButton compoutButton, boolean isChecked) {
                // TODO Auto-generated method stub
                callBlockOptions.isChecked = isChecked;
            }
        });
    }
    else if (c == TextView.class)
    {
        TextView textView = (TextView)(listView.getChildAt(x));
        textView.setOnEditorActionListener(new OnEditorActionListener(){

            @Override
            public boolean onEditorAction(TextView tView, int arg1, KeyEvent arg2) {
                // TODO Auto-generated method stub
                callBlockOptions.name = tView.getText().toString();
                return true;
            }

        });
    }

你可能希望你的其他类(class)是这样的:

public class callBlockOptions {
     public static String name;
     public static Boolean isChecked;
}

然后你可以像这样获取和设置 name 和 isChecked :

callBlockOptions.isChecked = false;
Boolean boolVal = callBlockOptions.isChecked;
