我在android自定义textview中设置了多个标志属性,如何使用TypedArray恢复属性
<some.text.view.that.i.defined.TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
font:sanFrancisco="bold|italic"/>
<attr name="fontSanFrancisco">
<flag name="regular" value="0"/>
<flag name="bold" value="1"/>
<flag name="italic" value="2"/>
</attr>
<declare-styleable name="font">
<attr name="sanFrancisco" format="flag"/>
</declare-styleable>

<flag name="regular" value="0" />
<flag name="bold" value="1" />
<flag name="italic" value="2" />
</attr>
</resources>
<强> activity_main.xml中强>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"

android:layout_height="fill_parent"
android:gravity="center">
<com.example.checkstack.MyView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Hello World"
android:layout_marginTop="20dip"/>
</LinearLayout>
<强> MyView的强>
public class MyView extends TextView {
public MyView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
applyCustomFont(context, attrs);
}
public MyView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
applyCustomFont(context, attrs);
}
private void applyCustomFont(Context context, AttributeSet attrs) {
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.font);
int textStyle = a.getInt(R.styleable.font_my_sampleFlag, 1);
setTypeface(null, textStyle);
a.recycle();
}
}

尝试这样的事情:
int style = attrs.getInteger( R.styleable.HighlightedTextView_highlightStyle, -1 );
if( style >= 0 ) {
setHighlightStyle( style );
}
attrs.recycle();
}
