(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)
代码语言:javascript复制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
代码语言:javascript复制 <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
代码语言:javascript复制<com.*******.TitleView
android:id="@ id/title"
android:layout_width="match_parent"
android:layout_height="48dp"
app:name="订单"/>//-----------------添加app:
