Android带Radio选项、确定、取消按钮的上下文菜单的实现

来源：互联网发布：腾讯云绑定域名有冲突编辑：程序博客网时间：2024/06/14 10:10

在应用的实现过程中，需要弹出上下文对话框选择，提供用户选择的Radio，还有确定和取消按钮。

1、在布局文件中增加

android:onClick="onShowDialogClick1"

2、源码中增加对应的响应函数，以下代码是我的项目中用到的，只做参考

     public void onShowDialogClick1(View v){
             AlertDialog.Builder builder = new AlertDialog.Builder(this);
             EmptyListener l = new EmptyListener();
             SyncListener synclis=new SyncListener(0);//0表示上传
             this.allOrfresh=1;

             //设置Dialog的标题
             builder.setTitle(R.string.card_select);
             //设置可供选择的ListView
             builder.setSingleChoiceItems(R.array.select_backups,1, new DialogInterface.OnClickListener() {
                 //@Override
                 public void onClick(DialogInterface dialog, int which) {
                     //which是选中的位置(基于0的)
                   if(which==0)
                   {
                       allOrfresh=0;
                   }else
                   {
                       allOrfresh=1;
                   }
                     String[] items = getResources().getStringArray(R.array.select_backups);
                     Toast.makeText(AndroidSyncPhonebook.this, items[which], Toast.LENGTH_LONG).show();
                 }
             });

             builder.setPositiveButton(R.string.dialog_ok, synclis);
             builder.setNegativeButton(R.string.dialog_cancel, l);
             AlertDialog ad = builder.create();
             ad.show();
       }

     //空的监听类
     private class EmptyListener implements DialogInterface.OnClickListener{
         //@Override
             public void onClick(DialogInterface dialog, int which) {
            }
        }

     private class SyncListener implements DialogInterface.OnClickListener {
         private int idx;
         private int syncMode = 0;
         private int m_count = 0;
         private int i=0;
         public SyncListener(int idx) {
             this.idx = idx;
         }
         public void onClick(DialogInterface dialog, int which) {
           Log.d("d","allOrfresh="+allOrfresh);
           // Log.debug(TAG, "Clicked on item: " + idx + " hasFocus=" + v.hasFocus());
                if(this.idx==0) {
                    if(allOrfresh==0){ }
                    else{ }
                }
                else if(this.idx==1) { }
                else if(this.idx==2) { }
                 Log.d("d","syncmode="+syncMode);
                 homeScreenController.buttonPressed(0,syncMode);
         }
    }
