我正在尝试构建单选按钮输入活动。我已经做了一切在 http://developer.android.com/guide/topics/ui/controls/radiobutton.html获取RadioButton无法解析为类型
但我越来越描述“单选按钮不能被解析为一个类型”中 布尔检查=((单选)查看).isChecked错误();线。 “((RadioButton)视图)”下的红线部分。我错过了什么?请帮忙。
package com.my.test;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
public class Main1 extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main1);
}
public void onRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();
int a; // store the value corresponding to the RadioButton which is clicked
switch(view.getId()) {
case R.id.radio1:
if (checked)
a = 3;
break;
case R.id.radio2:
if (checked) a = 2;
break;
case R.id.radio3:
if (checked) a = 1;
break;
case R.id.radio4:
if (checked) a = 0;
break;
}
Intent intent = new Intent(this, Test2.class);
intent.putExtra("inputValue", a); // pass "a" to the next Activity
}
}
您是否导入了RadioButton类? –
