我有三个复选框，如下所示

Facebook CheckBox1 GooglePlus CheckBox2 Twitter CheckBox3

我试过下面的代码：

if (facebookChackbox.isChecked()) 
    {
        facebook_checkbox = true;

        AppUtil.facebookNetworkList_EditPost ="Facebook";
        list.add("facebook");
        Intent i = new Intent();
        i.putExtra("facebook_boolean", true);
        Log.e("facebook checkbox", "facebook checkbox" + facebook_checkbox);
    }
    else
    {
        AppUtil.facebookNetworkList_EditPost ="";
    }
    if (twitterChackbox.isChecked()) 
    {
        twitter_checkbox = true;
        AppUtil.twitterNetworkList_EditPost ="Twitter";
        list.add("twitter");
        Intent i = new Intent();
        i.putExtra("twitter_boolean", true);
        Log.e("twitter  checkbox", "twitter  checkbox" + twitter_checkbox);

    }
    else
    {
        AppUtil.twitterNetworkList_EditPost ="";
    }
    if (googleChackbox.isChecked()) 
    {
        AppUtil.gpNetworkList_EditPost ="Google Plus";
        googleplus_checkbox = true;
        list.add("gplus");
        Intent i = new Intent();
        i.putExtra("google_plus_boolean", true);
        Log.e("google plus checkbox", "google plus checkbox" + googleplus_checkbox);

    }
    else
    {
        AppUtil.gpNetworkList_EditPost ="";
    }

    AppUtil.SocialNetworkingList_EditPost = AppUtil.facebookNetworkList_EditPost+""+AppUtil.twitterNetworkList_EditPost+""+AppUtil.gpNetworkList_EditPost;

我已经在 APPUTIL 类中声明了所有这些静态字符串。

当我检查所有复选框或一两个复选框时，它给我 null，null，null 取决于检查 chechk 框。

我想要选中复选框的复选框的值。

private void processCheckboxes() {
    // TODO Auto-generated method stub

    list = new ArrayList<String>();
    sb = new StringBuilder();

    if (facebookChackbox.isChecked()) 
    {
        facebook_checkbox = true;

        AppUtil.facebookNetworkList_EditPost ="Facebook";
        list.add("facebook");
        Intent i = new Intent();
        i.putExtra("facebook_boolean", true);
        Log.e("facebook checkbox", "facebook checkbox" + facebook_checkbox);
    }
    else
    {
        AppUtil.facebookNetworkList_EditPost ="";
    }
    if (twitterChackbox.isChecked()) 
    {
        twitter_checkbox = true;
        AppUtil.twitterNetworkList_EditPost ="Twitter";
        list.add("twitter");
        Intent i = new Intent();
        i.putExtra("twitter_boolean", true);
        Log.e("twitter  checkbox", "twitter  checkbox" + twitter_checkbox);

    }
    else
    {
        AppUtil.twitterNetworkList_EditPost ="";
    }
    if (googleChackbox.isChecked()) 
    {
        AppUtil.gpNetworkList_EditPost ="Google Plus";
        googleplus_checkbox = true;
        list.add("gplus");
        Intent i = new Intent();
        i.putExtra("google_plus_boolean", true);
        Log.e("google plus checkbox", "google plus checkbox" + googleplus_checkbox);

    }
    else
    {
        AppUtil.gpNetworkList_EditPost ="";
    }

    AppUtil.SocialNetworkingList_EditPost = AppUtil.facebookNetworkList_EditPost+""+AppUtil.twitterNetworkList_EditPost+""+AppUtil.gpNetworkList_EditPost;


    for (int zz = 0; zz < list.size(); zz++) {

        network = list.get(zz);

        if (zz < list.size() - 1) 
        {

            Log.i("list.size()",""+list.size());
            Log.i("list.size() - 1",""+list.size());
            Log.i("network",""+network);

            sb.append(network + "," + network + "," + network);

            Log.i("sb",""+sb);
        } 
        else
        {
            Log.e("log", "List----" + zz + network);
            network_list = network;

            network_list = network + "," + network + "," + network;
            // network_list=network+""+network+"&gplus="+network+"&twitter"+
            // "" +network;

            sb.append(network + "," + network + "," + network);
        }
    }
}

以上是我现在调用的方法，我想将检查的值存储在字符串中，并想用它来设置文本。但是我得到了 facebookfacebook，意味着正在重复字符串。

yourcheckBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {             

                if (isChecked) {
                    //do something when checkbox is checked
                }
                else {          
                    //do something when checkbox is unchecked
                }
            }});

使用这些内置的复选框更改侦听器您可以轻松通知所有复选框的更改

为代码中的所有三个复选框创建checkedchangelistener .Friend
