中间的selector

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_checked="true"> <shape> <solid android:color="@color/green"/> </shape> </item> <item> <shape> <solid android:color="@color/white" /> <stroke android:width="1dp" android:color="@color/green" /> </shape> </item></selector>

右边的selector

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_checked="true"> <shape> <corners android:toPRightRadius="5dp" android:bottomRightRadius="5dp"/> <solid android:color="@color/green"/> </shape> </item> <item> <shape> <corners android:bottomRightRadius="5dp" android:topRightRadius="5dp" /> <solid android:color="@color/white" /> <stroke android:width="1dp" android:color="@color/green" /> </shape> </item></selector>

字体的selector

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:color="@color/white" android:state_checked="true"/> <item android:color="@color/white" android:state_focused="true"/> <item android:color="@color/white" android:state_pressed="true"/> <item android:color="@color/green"/></selector>

activity_main.xml ,上面是三个RadioButton,下面是button对应的layout

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <RadioGroup android:id="@+id/rg" android:layout_width="match_parent" android:layout_height="wrap_content" android:checkedButton="@+id/rb_train" android:gravity="center" android:padding="10dp" android:orientation="horizontal" > <RadioButton android:id="@+id/rb_train" android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:background="@drawable/sel_radio_left" android:button="@null" android:gravity="center" android:padding="10dp" android:text="培训" android:textColor="@drawable/sel_radio_text" android:textSize="12sp" /> <RadioButton android:id="@+id/rb_evaluate" android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:background="@drawable/sel_radio_mid" android:button="@null" android:gravity="center" android:padding="10dp" android:text="评测" android:textColor="@drawable/sel_radio_text" android:textSize="12sp" /> <RadioButton android:id="@+id/rb_examRecord" android:layout_width="0dp" android:layout_weight="1" android:layout_height="wrap_content" android:background="@drawable/sel_radio_right" android:button="@null" android:gravity="center" android:padding="10dp" android:text="考试记录" android:textColor="@drawable/sel_radio_text" android:textSize="12sp" /> </RadioGroup> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <LinearLayout android:id="@+id/ll_train" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="培训 " /> <ListView android:id="@+id/lv_train" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> <LinearLayout android:id="@+id/ll_evaluate" android:visibility="gone" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="评测 " /> <ListView android:id="@+id/lv_evaluate" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> <LinearLayout android:id="@+id/ll_examRecord" android:visibility="gone" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="考试记录 " /> <ListView android:id="@+id/lv_examRecord" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> </LinearLayout></LinearLayout>

MainActivity

package com.lzz.demoapplication;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.LinearLayout;import android.widget.RadioGroup;public class MainActivity extends AppCompatActivity implements RadioGroup.OnCheckedChangeListener { private RadioGroup rg; private LinearLayout ll_train,ll_evaluate,ll_examRecord; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); rg = (RadioGroup) findViewById(R.id.rg); rg.setOnCheckedChangeListener(this); ll_train = (LinearLayout) findViewById(R.id.ll_train); ll_evaluate = (LinearLayout) findViewById(R.id.ll_evaluate); ll_examRecord = (LinearLayout) findViewById(R.id.ll_examRecord); } @Override public void onCheckedChanged(RadioGroup radioGroup, int checkedId) { if (checkedId == R.id.rb_train) { clickTrain(); } else if (checkedId == R.id.rb_evaluate) { clickEvaluate(); } else if (checkedId == R.id.rb_examRecord) { clickExamRecord(); } } private void clickExamRecord() { ll_train.setVisibility(View.GONE); ll_evaluate.setVisibility(View.GONE); ll_examRecord.setVisibility(View.VISIBLE); } private void clickEvaluate() { ll_train.setVisibility(View.GONE); ll_evaluate.setVisibility(View.VISIBLE); ll_examRecord.setVisibility(View.GONE); } private void clickTrain() { ll_train.setVisibility(View.VISIBLE); ll_evaluate.setVisibility(View.GONE); ll_examRecord.setVisibility(View.GONE); }}
