下面给出Demo,直观见到两个控件如何使用
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<CheckBox
android:id="@+id/checkBox1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="@string/apple" />
<CheckBox
android:id="@+id/checkBox2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/banana" />
<RadioGroup
android:id="@+id/radioGroup1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<RadioButton
android:id="@+id/radioButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="@string/man" />
<RadioButton
android:id="@+id/radioButton2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/women" />
</RadioGroup>
</LinearLayout>
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.RadioGroup;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity implements android.widget.RadioGroup.OnCheckedChangeListener{
private CheckBox cb;
private RadioGroup rg;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//初始化控件
cb = (CheckBox) findViewById(R.id.checkBox1);
rg = (RadioGroup) findViewById(R.id.radioGroup1);
//绑定事件
cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
//button 被操作的控件,isChecked为 android:checked="true"
@Override
public void onCheckedChanged(CompoundButton button, boolean isChecked) {
if(isChecked){
String text = button.getText().toString();
Toast.makeText(MainActivity.this, "男", Toast.LENGTH_SHORT).show();
Log.i("Tag",text);
}
}
});
rg.setOnCheckedChangeListener(this);
}
//radioGroup Radio组,radioId 子控件的ID
@Override
public void onCheckedChanged(RadioGroup radioGroup, int radioId) {
switch(radioId){
case R.id.radioButton1:
Toast.makeText(this, "男", Toast.LENGTH_SHORT).show();
break;
case R.id.radioButton2:
Toast.makeText(this, "女", Toast.LENGTH_SHORT).show();
break;
default :break;
}
}
}
