(仅仅只是整理,以后用到直接来翻就行了) 比如有这样一个自定义控件(layout文件就不看了)
public class TitleView extends LinearLayout { public ImageView themeTitleLeft; private TextView themeTitle; private ImageView themeTitleRight; public TitleView(Context context) { this(context, null); } public TitleView(final Context context, AttributeSet attrs) { super(context, attrs); inflate(context, R.layout.theme_title, this); themeTitle = (TextView) findViewById(R.id.theme_title); themeTitleLeft = (ImageView) findViewById(R.id.theme_title_left); themeTitleRight = (ImageView) findViewById(R.id.theme_title_right); TypedArray ta = context.obtainStyledAttributes(attrs, R.styleable.title); String name = ta.getString(R.styleable.title_name); themeTitle.setText(name); ta.recycle(); } }那R.styleable.title和R.styleable.title_name又是怎么配置的呢? 当然是在values文件夹下新建attrs.xml
<declare-styleable name="title"> <attr name="name" format="string"/> </declare-styleable>生成TypedArray是用的declare-styleable的name,生成对应的string是在两个name中加下划线 用法
<com.*******.TitleView android:id="@+id/title" android:layout_width="match_parent" android:layout_height="48dp" app:name="订单"/>//-----------------添加app:
