原因接收和QUOT; RadioGroup中是不适用的论点＆QUOT; [英] Reasons for receiving "RadioGroup is not applicable for the arguments"

问题描述

我在执行 RadioGroup中在我的应用即可。对于我已导入进口android.widget.RadioGroup 和实施OnCheckedChangeListener 。不过还是我得到这个错误：

  

该方法
  setOnCheckedChangeListener（RadioGroup.OnCheckedChangeListener）在
  类型RadioGroup中是不适用的参数（OpenedClass）

Java的：

  

OpenedClass.java

 公共类OpenedClass扩展活动实现OnClickListener，OnCheckedChangeListener {    TextView的TV1，TV2;
    RadioGroup中selectionList;
    按钮RTN;
    串gotBread;
    @覆盖
    保护无效的onCreate（捆绑savedInstanceState）{
        // TODO自动生成方法存根
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.send）;
        initlize（）;
        捆绑gotBusket = getIntent（）getExtras（）。
        gotBread = gotBusket.getString（KEY）;
        tv1.setText（gotBread）;    }
    私人无效initlize（）{
        // TODO自动生成方法存根        TV1 =（的TextView）findViewById（R.id.tvQuestion）;
        TV2 =（的TextView）findViewById（R.id.textView2）;
        RTN =（按钮）findViewById（R.id.bReturn）;
        rtn.setOnClickListener（本）;
        selectionList =（RadioGroup中）findViewById（R.id.rgAnswers）;
        selectionList.setOnCheckedChangeListener（本）;
    }
    @覆盖
    公共无效的onClick（查看为arg0）{
        // TODO自动生成方法存根    }
    @覆盖
    公共无效onCheckedChanged（CompoundButton为arg0，ARG1布尔）{
        // TODO自动生成方法存根        开关（arg0.getId（））
        {
        案例R.id.rCrazy：
            打破;
        案例R.id.rSuper：
            打破;
        案例R.id.rBoth：
            打破;
        }    }}
 

解决方案

您导入了不正确的类 OnCheckedChangeListener 为 RadioGroup中。

替换为：

 进口android.widget.CompoundButton.OnCheckedChangeListener;
 

这一个：

 进口android.widget.RadioGroup.OnCheckedChangeListener;
 

和解决如下的接口实现：

  @覆盖
公共无效onCheckedChanged（RadioGroup中组，诠释checkedId）{
   开关（checkedId）
   {
      //你的情况下，
   }
}
 

I am implementing RadioGroup in my application. For that I have imported import android.widget.RadioGroup and implemented OnCheckedChangeListener. But still I am getting this error:

The method setOnCheckedChangeListener(RadioGroup.OnCheckedChangeListener) in the type RadioGroup is not applicable for the arguments (OpenedClass)

Java:

OpenedClass.java

public class OpenedClass extends Activity implements OnClickListener,OnCheckedChangeListener{

    TextView tv1,tv2;
    RadioGroup selectionList;
    Button rtn;
    String gotBread;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.send);
        initlize();
        Bundle gotBusket = getIntent().getExtras();
        gotBread = gotBusket.getString("KEY");
        tv1.setText(gotBread);

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

        tv1 = (TextView)findViewById(R.id.tvQuestion);
        tv2 = (TextView)findViewById(R.id.textView2);
        rtn = (Button)findViewById(R.id.bReturn);
        rtn.setOnClickListener(this);
        selectionList = (RadioGroup)findViewById(R.id.rgAnswers);
        selectionList.setOnCheckedChangeListener(this);
    }
    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub

    }
    @Override
    public void onCheckedChanged(CompoundButton arg0, boolean arg1) {
        // TODO Auto-generated method stub

        switch(arg0.getId())
        {
        case R.id.rCrazy:
            break;
        case R.id.rSuper:
            break;
        case R.id.rBoth:
            break;
        }

    }



}

解决方案

You are importing an incorrect class of OnCheckedChangeListener for RadioGroup.

Replace:

import android.widget.CompoundButton.OnCheckedChangeListener;

with this one:

import android.widget.RadioGroup.OnCheckedChangeListener;

and fix your interface implementation as below:

@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
   switch(checkedId)
   {
      //your cases
   }
}
