以编程方式更改可绘制按钮 [英] Change Button Drawable Programmatically

问题描述

我有一个左侧可绘制的按钮:

 <按钮android:id ="@ + id/post_feeling_btn"android:background ="@ color/white"android:layout_width ="match_parent"android:layout_height ="wrap_content"android:padding ="4dp"android:drawableLeft ="@ drawable/feeling_btn"android:gravity ="left | center_vertical"android:textColor ="@ color/gray"android:text ="Sentimento"/> 

在我的恢复方法中，我以编程方式更改了按钮的文本:

 按钮setFeeling;感觉按钮已选择感觉；@Override公共无效onResume(){super.onResume();selectedFeeling =(((FeedActivity)getActivity()).getSelectedFeeling();if(selectedFeeling！= null){setFeeling.setText(selectedFeeling.getFeeling());}} 

是否有一种方法可以使用我的selectedFeeling对象中具有的图像来改变我的可绘制对象的左侧并以相同的方法设置图像?我正在寻找类似的东西:

  setFeeling.setDrawable(); 

解决方案

尝试如下操作:对于 drawableLeft

  int imgResource = R.drawable.your_drawable;setFeeling.setCompoundDrawablesWithIntrinsicBounds(imgResource，0，0，0);setFeeling.setCompoundDrawablePadding(8);//用于填充 

感谢答案在这里.

I have a button with drawable left:

<Button
    android:id="@+id/post_feeling_btn"
    android:background="@color/white"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="4dp"
    android:drawableLeft="@drawable/feeling_btn"
    android:gravity="left|center_vertical"
    android:textColor="@color/gray"
    android:text="Sentimento"/>

In my on resume method, I change the button's text programmatically:

Button setFeeling;
FeelingButton selectedFeeling;

@Override
public void onResume() {
    super.onResume();
    selectedFeeling = ((FeedActivity)getActivity()).getSelectedFeeling();
    if(selectedFeeling != null){
        setFeeling.setText(selectedFeeling.getFeeling());
    }
}

Is there a way to change my drawable left and set the image in the same method, using the image I have in my selectedFeeling object? I'm looking for something like:

setFeeling.setDrawable();

解决方案

try something like this: for drawableLeft

int imgResource = R.drawable.your_drawable;
setFeeling.setCompoundDrawablesWithIntrinsicBounds(imgResource, 0, 0, 0);
setFeeling.setCompoundDrawablePadding(8);     //for padding
