        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);

        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);

a.recycle();
