仿今日头条，FrameLayout+RadioGroup实现联动

MaiActivity:xml布局

<FrameLayout    android:id="@+id/fram_layout"    android:layout_width="match_parent"    android:layout_height="0dp"    android:layout_weight="8.5"></FrameLayout><RadioGroup    android:id="@+id/rg"    android:layout_width="match_parent"    android:layout_height="0dp"    android:layout_weight="1.5"    android:orientation="horizontal">    <RadioButton        android:id="@+id/rbtn1"        android:layout_width="0dp"        android:layout_height="match_parent"        android:button="@null"        android:checked="true"        android:text="首页"       android:drawableTop="@drawable/img_selector"        android:layout_weight="1"        android:gravity="center"        />    <RadioButton        android:id="@+id/rbtn2"        android:layout_width="0dp"        android:layout_height="match_parent"        android:button="@null"        android:drawableTop="@drawable/img_yaowen"        android:text="发现"        android:layout_weight="1"        android:gravity="center"        />    <RadioButton        android:id="@+id/rbtn3"        android:layout_width="0dp"        android:layout_height="match_parent"        android:button="@null"        android:drawableTop="@drawable/img_login"        android:text="登录"        android:layout_weight="1"        android:gravity="center"        /></RadioGroup>

selector选择器

drawable目录下

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:state_checked="true" android:drawable="@drawable/user_1"/>    <item android:state_checked="false" android:drawable="@drawable/user_0"/>    <item android:drawable="@drawable/user_0"/></selector>

其余三个同理

xml布局

<EditText        android:layout_width="match_parent"        android:layout_height="30dp"        android:textSize="14dp"        android:layout_gravity="center_vertical"        android:background="@drawable/shape_stly"        android:hint="在线泡水|两个萌娃|荒岛惊魂"/></LinearLayout>

EditText用shape的样式

shape xmlns:android="http://schemas.android.com/apk/res/android"><solid android:color="#fff" ></solid>    <corners android:radius="10dp"/>    <stroke android:color="#000" android:width="1dp"/></shape>

java代码

protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main2);    frameLayout = (FrameLayout) findViewById(R.id.fram_layout);    radioGroup = (RadioGroup) findViewById(R.id.rg);//默认显示第一页    getSupportFragmentManager().beginTransaction().replace(R.id.fram_layout,new HomeFragment()).commit();    radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {        @Override        public void onCheckedChanged(RadioGroup radioGroup, @IdRes int i) {            switch (i){                case R.id.rbtn1:                    getSupportFragmentManager().beginTransaction().replace(R.id.fram_layout,new HomeFragment()).commit();                    break;                case R.id.rbtn2:                    getSupportFragmentManager().beginTransaction().replace(R.id.fram_layout,new YaowenFragment()).commit();                    break;                case R.id.rbtn3:                    getSupportFragmentManager().beginTransaction().replace(R.id.fram_layout,new LoginFragment()).commit();                    break;                default:                    break;            }        }    });}
