Android RadioButton 图片位置与大小
Java:
rgGroup = (RadioGroup) findViewById(R.id.re_group); rbWeiHui = (RadioButton) findViewById(R.id.rb_wei_hui); rbAdd = (RadioButton) findViewById(R.id.rb_add); rbMine = (RadioButton) findViewById(R.id.rb_mine); //定义底部标签图片大小 Drawable drawableWeiHui = getResources().getDrawable(R.drawable.btn_tab_wei_hui_selector); drawableWeiHui.setBounds(0, 0, 69, 69);//第一0是距左右边距离,第二0是距上下边距离,第三69长度,第四宽度 rbWeiHui.setCompoundDrawables(null, drawableWeiHui, null, null);//只放上面 Drawable drawableAdd = getResources().getDrawable(R.drawable.btn_tab_add_selector); drawableAdd.setBounds(0, 0, 168, 120); rbAdd.setCompoundDrawables(drawableAdd, null, null, null); Drawable drawableRight = getResources().getDrawable(R.drawable.btn_tab_mine_selector); drawableRight.setBounds(0, 0, 69, 69); rbMine.setCompoundDrawables(null, drawableRight, null, null); //初始化底部标签 rgGroup.check(R.id.rb_wei_hui);// 默认勾选首页,初始化时候让首页默认勾选
xml:
<RadioGroup android:id="@+id/re_group" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/app_bg_color" android:orientation="horizontal" > <RadioButton android:id="@+id/rb_wei_hui" style="@style/BottomTabStyle" android:layout_marginTop="5dp" android:drawableTop="@drawable/btn_tab_wei_hui_selector" android:textSize="12sp" android:text="xx" /> <RadioButton android:id="@+id/rb_add" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@color/app_bg_color" android:button="@null" android:drawableTop="@mipmap/ic_add_selected" android:gravity="center" android:paddingTop="10dip" /> <RadioButton android:id="@+id/rb_mine" style="@style/BottomTabStyle" android:layout_marginTop="5dp" android:drawableTop="@drawable/btn_tab_mine_selector" android:textSize="12sp" android:text="xx" /> </RadioGroup>
selected:只写一个selected,其它模仿此
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:drawable="@mipmap/ic_mine_selected" android:state_checked="true" /> <item android:drawable="@mipmap/ic_mine_normal" /> </selector>
style:共同的style-中间的是定制的,左右一个风格
<!-- 低栏RadioButton首页下面的标签的样式 --> <style name="BottomTabStyle"> <item name="android:layout_width">wrap_content</item> <item name="android:layout_height">wrap_content</item> <item name="android:layout_gravity">center_vertical</item> <item name="android:button">@null</item> <item name="android:padding">5dp</item> <item name="android:drawablePadding">3dp</item> <item name="android:textColor">@drawable/btn_tab_text_selector</item> <item name="android:layout_weight">1</item> <item name="android:gravity">center</item> <item name="android:layout_marginTop">5dp</item> </style>
