iniview(Context context)初始化自定义的布局文件
根据需求自定义一些API方法
public class SettingItemView extends RelativeLayout { private CheckBox cb_status; private TextView tv_title; private TextView tv_desc; private String title; private String desc_on; private String desc_off; public void iniview(Context context){ View.inflate(context, R.layout.setting_item_view, this); cb_status = (CheckBox)findViewById(R.id.cb_status); tv_title = (TextView)findViewById(R.id.tv_title); tv_desc = (TextView)findViewById(R.id.tv_desc); } public SettingItemView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); iniview(context); } public SettingItemView(Context context, AttributeSet attrs) { super(context, attrs); iniview(context); title = attrs.getAttributeValue("http://schemas.android.com/apk/res/com.victor.mobilesafe","title"); desc_on = attrs.getAttributeValue("http://schemas.android.com/apk/res/com.victor.mobilesafe","desc_on"); desc_off = attrs.getAttributeValue("http://schemas.android.com/apk/res/com.victor.mobilesafe","desc_off"); tv_title.setText(title); setDesc(desc_off); } public SettingItemView(Context context) { super(context); iniview(context); } public boolean isChecked(){ return cb_status.isChecked(); } public void setChecked(boolean checked){ if (checked) { setDesc(desc_on); }else{ setDesc(desc_off); } cb_status.setChecked(checked); } public void setDesc(String text){ tv_desc.setText(text); }}
别忘记声明自定义命名空间
xmlns:victor="http://schemas.android.com/apk/res/com.victor.mobilesafe"
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:victor="http://schemas.android.com/apk/res/com.victor.mobilesafe" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <com.victor.mobilesafe.ui.SettingItemView android:id="@+id/siv_update" android:layout_width="wrap_content" android:layout_height="wrap_content" victor:desc_off="自动更新关闭" victor:desc_on="自动更新开启" victor:title="设置自动更新" > </com.victor.mobilesafe.ui.SettingItemView></LinearLayout>
itheima:title="设置自动更新" itheima:desc_on="设置自动更新已经开启" itheima:desc_off="设置自动更新已经关闭"
