andorid TextView(1)-带图片的TextView

1.带图片的TextView

1.在xml中设置属性

<TextView
android:id="@+id/my_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/drawable_shape1"
android:drawableBottom="@mipmap/ic_launcher"
android:drawableLeft="@mipmap/ic_launcher"
android:drawableRight="@mipmap/ic_launcher"
android:drawableTop="@mipmap/ic_launcher"
android:text="22222"
android:textColor="#ffffff"/>

2.如果需要设置图片大小,只能在代码中设置

//Returns drawables for the left, top, right, and bottom borders.
Drawable[] compoundDrawables = mMy_Tv.getCompoundDrawables();
for (int i = 0; i < compoundDrawables.length; i++) {
    if(i == 3){
        //This is where the drawable will draw when its draw() method is called.
        compoundDrawables[i].setBounds(0,0,200,200);
    }
}

这里需要注意的是设置完位置之后,需要重新调用setCompoundDrawables()方法,否则图片会变成这样:

3.重新设置:

//重新设置    如果没有图片用null代替
mMy_Tv.setCompoundDrawables(compoundDrawables[0], compoundDrawables[1], compoundDrawables[2]
,compoundDrawables[3]);
