一、LinearLayout 视图页面

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/activity_app10"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <LinearLayout        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:orientation="horizontal">        <CheckBox            android:id="@+id/checkbox1"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="篮球" />        <CheckBox            android:id="@+id/checkbox2"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="足球" />        <CheckBox            android:id="@+id/checkbox3"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="羽毛球" />    </LinearLayout>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="vertical"        android:gravity="center">        <Button            android:id="@+id/button1"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="获取复选框数据"            android:layout_marginTop="20dp"            android:padding="10dp"            android:textSize="18sp"            android:textColor="#fff"            android:background="@drawable/button_shape"/>    </LinearLayout>    <LinearLayout        android:orientation="vertical"        android:layout_width="wrap_content"        android:layout_height="wrap_content">        <RadioGroup            android:layout_width="wrap_content"            android:layout_height="wrap_content">            <RadioButton                android:id="@+id/man"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="男"/>            <RadioButton                android:id="@+id/woman"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="女"/>        </RadioGroup>    </LinearLayout>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="vertical"        android:gravity="center">        <Button            android:id="@+id/button2"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:background="@drawable/button_shape"            android:textSize="18sp"            android:textColor="#fff"            android:padding="10dp"            android:layout_marginTop="20dp"            android:text="获取单选框的值"/>    </LinearLayout></LinearLayout>

二、入口文件

import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.CheckBox;import android.widget.RadioButton;import android.widget.Toast;import java.util.ArrayList;import java.util.List;public class App10 extends AppCompatActivity {    //定义按钮与复选框及List    private Button button1, button2;    private CheckBox checkbox1, checkbox2, checkbox3;    private RadioButton man, woman;    private List<CheckBox> checkBoxList = new ArrayList<>();    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_app10);        //初始化控件        checkbox1 = (CheckBox) findViewById(R.id.checkbox1);        checkbox2 = (CheckBox) findViewById(R.id.checkbox2);        checkbox3 = (CheckBox) findViewById(R.id.checkbox3);        button1 = (Button) findViewById(R.id.button1);        button2 = (Button) findViewById(R.id.button2);        man = (RadioButton) findViewById(R.id.man);        woman = (RadioButton) findViewById(R.id.woman);        //追加到checkBoxList中        checkBoxList.add(checkbox1);        checkBoxList.add(checkbox2);        checkBoxList.add(checkbox3);        button1.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                StringBuffer sb = new StringBuffer();                for (CheckBox checkbox : checkBoxList) {                    if (checkbox.isChecked()) {                        sb.append(checkbox.getText().toString() + "-");                    }                }                if (sb != null && "".equals(sb.toString())) {                    Toast.makeText(getApplicationContext(), "至少选择一个", Toast.LENGTH_LONG).show();                } else {                    Toast.makeText(getApplicationContext(), "你选择的是:" + sb.toString(), Toast.LENGTH_LONG).show();                }            }        });        button2.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if(man.isChecked()){                    Toast.makeText(getApplicationContext(),"你选择的是男",Toast.LENGTH_LONG).show();                }else if(woman.isChecked()){                    Toast.makeText(getApplicationContext(),"你选择的是女",Toast.LENGTH_LONG).show();                }else {                    Toast.makeText(getApplicationContext(),"你还没选择",Toast.LENGTH_LONG).show();                }            }        });    }}

三、边框圆角

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android">    <solid android:color="#f00"/>    <stroke android:width="1dp" android:color="#630"/>    <corners android:radius="5dp"/></shape>
