java代码：

Values attrs

<?xml version="1.0" encoding="utf-8"?><resources>    <attr name="TitleText" format="string|reference"/>    <attr name="TitleTextColor" format="color|reference"/>    <attr name="TitleTextSize" format="dimension|reference"/>    <declare-styleable name="TestTitleView">        <attr name="TitleText"/>        <attr name="TitleTextColor"/>        <attr name="TitleTextSize"/>    </declare-styleable></resources>

View代码：

/** * Created by aierJun on 2017/2/15. */public class TestTitleView extends RelativeLayout {    private TextView back;    private TextView title;    public TestTitleView(Context context) {        super(context);    }    public TestTitleView(Context context, AttributeSet attrs) {        super(context, attrs);        LayoutInflater.from(context).inflate(R.layout.test_text_title_view, this);        back= (TextView)findViewById(R.id.back_test_view);        title= (TextView)findViewById(R.id.title_test_view);        TypedArray a=context.obtainStyledAttributes(attrs,R.styleable.TestTitleView);        int textColor=a.getColor(R.styleable.TestTitleView_TitleTextColor, Color.BLUE);        String textText=a.getString(R.styleable.TestTitleView_TitleText);        float textSize=a.getDimension(R.styleable.TestTitleView_TitleTextSize,25);        title.setTextSize(textSize);        title.setTextColor(textColor);        title.setText(textText);        a.recycle();    }    public TestTitleView(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);    }    public void setBackOnClickLister(OnClickListener lister){        back.setOnClickListener(lister);    }}

Layout代码：

 <com.aierjun.test.view.TestTitleView        android:id="@+id/test_testtitleview"        android:layout_width="match_parent"        android:layout_height="wrap_content"        app:TitleTextSize="19sp"        app:TitleText="aierjun">    </com.aierjun.test.view.TestTitleView>

注意：

 TypedArray a=context.obtainStyledAttributes(attrs,R.styleable.TestTitleView);

最后

a.recycle();
