TextView的xml
- <TextView
- android:id="@+id/textciew1"
- android:layout_width="match_parent"
- android:layout_height="wrap_content"
- android:background="#000"
- android:drawableRight="@drawable/button_nav_down"
- android:gravity="center_vertical"
- android:paddingLeft="16dp"
- android:paddingRight="16dp"
- android:text="展开"
- android:textColor="#fff"
- />
但是API提示,setCompoundDrawables() 调用的时候,Drawable对象必须调用setBounds(int left, int top, int right, int bottom)方法,于是我们加一行代码就可以了
- nav_up.setBounds(0, 0, nav_up.getMinimumWidth(), nav_up.getMinimumHeight());
代码合在一起是这样的:
- Drawable nav_up=getResources().getDrawable(R.drawable.button_nav_up);
- nav_up.setBounds(0, 0, nav_up.getMinimumWidth(), nav_up.getMinimumHeight());
- textview1.setCompoundDrawables(null, null, nav_up, null);
