You can use the function below:
您可以使用以下功能：
editText.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.drawableRight, 0);
or (if you want to pass the drawable itself instead of its ID)
或者（如果你想传递drawable本身而不是它的ID）
editText.setCompoundDrawablesWithIntrinsicBounds(null, null, ContextCompat.getDrawable(context,R.drawable.drawableRight), null)
The order of params corresponding to the drawable location is: left, top, right, bottom
drawable位置对应的params顺序为：左、上、右、下

在这里找到更多
EditText myEdit = (EditText) findViewById(R.id.myEdit);
myEdit.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.icon, 0);
// where params are (left,top,right,bottom)
You can also set drawable padding programmatically:
您还可以以编程方式设置可绘制填充：
myEdit.setCompoundDrawablePadding("Padding value");

Try like below:
尝试如下：
Drawable img = getContext().getResources().getDrawable( R.drawable.smiley );
EdtText.setCompoundDrawablesWithIntrinsicBounds( 0, 0, img, 0);
Edit :
编辑 ：
int img = R.drawable.smiley;
EdtText.setCompoundDrawablesWithIntrinsicBounds( 0, 0, img, 0);

Try:
尝试：
EditText editFirstname = (EditText) findViewById(R.id.edit_fname);
Drawable icUser = getResources().getDrawable(R.drawable.ic_user);
editFirstname.setCompoundDrawablesWithIntrinsicBounds(null, null, icUser, null);
Then you can add a touch listener to that specific drawable.
然后，您可以向该特定可绘制对象添加触摸侦听器。

int img = R.drawable.smiley;
editText.setCompoundDrawables( null, null, img, null );
Explained here
在这里解释
setCompoundDrawablesWithIntrinsicBounds (int left, int top, int right, int bottom)
Sets the Drawables (if any) to appear to the left of, above, to the right of, and below the text. Use 0 if you do not want a Drawable there. The Drawables' bounds will be set to their intrinsic bounds.
将 Drawables（如果有）设置为出现在文本的左侧、上方、右侧和下方。如果您不想在那里使用 Drawable，请使用 0。Drawables 的边界将设置为它们的内在边界。

You can use your editText view (here it is txview) built in function setCompoundDrawablesWithIntrinsicBounds() to do what you are looking for
您可以使用内置函数 setCompoundDrawablesWithIntrinsicBounds() 的 editText 视图（这里是 txview）来执行您要查找的操作
in my code I Used it like this . txview.setCompoundDrawablesWithIntrinsicBounds(0,0,R.drawable.ic_arrow_drop_up,0);
在我的代码中，我像这样使用它。txview.setCompoundDrawablesWithIntrinsicBounds(0,0,R.drawable.ic_arrow_drop_up,0);
txview.setCompoundDrawablesWithIntrinsicBounds(left,top,right,bottom);

For changing left and right both at a time I use this single line.
为了一次改变左右，我使用这条线。
download.setCompoundDrawablesWithIntrinsicBounds( R.drawable.ic_lock_open_white_24dp, 0, R.drawable.ic_lock_open_white_24dp, 0);

If it requires android graphics drawable then this will work
如果它需要可绘制的 android 图形，那么这将起作用
Drawable dw = getApplicationContext().getResources().getDrawable(R.drawable.edit);
Button start = (Button)findViewById(R.id.buttonStart);
start.setCompoundDrawablesWithIntrinsicBounds(dw, null, null, null);

et_feedback.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
}
et_feedback.setCompoundDrawablesWithIntrinsicBounds(0,R.mipmap.feedback_new, 0, 0);
et_feedback.setTextColor(Color.BLACK);
}
});
Hide Drawable using this
使用这个隐藏 Drawable
et_feedback.setCompoundDrawablesWithIntrinsicBounds(0,0, 0, 0);
