RadioButton和CheckBox差不多,这里只写一个,因为我本身不是学andorid,所以就当给自己留一个备份,省的每次用到都需要代码敲一次,很麻烦
1.如果想选中时想改变颜色可以设置一个xml,我设置的upload_state_btn
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_checked="true" android:color="#0000ff"></item> <item android:color="#2a2a2a"></item> </selector>
使用
<RadioGroup android:layout_width="match_parent" android:layout_height="44dp" android:orientation="horizontal" android:id="@+id/group"> <RadioButton android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:text="男" android:button="@null" android:gravity="center" android:checked="true" android:enabled="false" android:textColor="@drawable/upload_state_btn" android:id="@+id/btn1" /> <RadioButton android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:text="女" android:button="@null" android:gravity="center" android:textColor="@drawable/upload_state_btn" android:id="@+id/btn2"/> </RadioGroup>
点击事件有两种方法
方法一:
RadioGroup group = (RadioGroup)findViewById(R.id.group); group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { @Override public void onCheckedChanged(RadioGroup group, int checkedId) { switch (checkedId){ case R.id.btn1: break; case R.id.btn2: break; } } });
方法二:
RadioButton btn1; RadioButton btn2; btn1 = (RadioButton)findViewById(R.id.btn1); btn2 = (RadioButton)findViewById(R.id.btn2); btn1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent startIntent = new Intent(DemoActivity.this, MyService.class); //startService启动形式 startService(startIntent); } }); btn2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent startIntent = new Intent(DemoActivity.this, MyService.class); //startService启动形式 stopService(startIntent); } });
如果需要改变系统自带的图标,可以添加xml
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@mipmap/checkbox_role" android:state_checked="true"/> <item android:drawable="@mipmap/checkbox_dis_role" android:state_checked="false"/> <item android:drawable="@mipmap/checkbox_dis_role"/> </selector>
在styles中添加:
<style name="CustomTheme" parent="@android:style/Widget.CompoundButton.RadioButton"> <item name="android:button">@drawable/custom_radio</item> </style>
使用的使用直接在xml RadioButton属性中添加一句:
style="@style/CustomTheme"
