How to programmatically set drawableRight on Android Edittext?

问题

I know about set drawableRight in XML. but i required to do it programmatically because it is change as per some condition.

回答1:

You can use the function below:

editText.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.drawableRight, 0);

or (if you want to pass the drawable itself instead of its 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

Find Further here

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:

myEdit.setCompoundDrawablePadding("Padding value");

回答3:

Try like below:

Drawable img = getContext().getResources().getDrawable( R.drawable.smiley );
EdtText.setCompoundDrawablesWithIntrinsicBounds( 0, 0, img, 0);

Edit :

 int img = R.drawable.smiley;
 EdtText.setCompoundDrawablesWithIntrinsicBounds( 0, 0, img, 0);

回答4:

int img = R.drawable.smiley;
editText.setCompoundDrawables( null, null, img, null );

Explained here

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.

Try:

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.

回答6:

You can use your editText view (here it is txview) built in function setCompoundDrawablesWithIntrinsicBounds() to do what you are looking for

in my code I Used it like this . txview.setCompoundDrawablesWithIntrinsicBounds(0,0,R.drawable.ic_arrow_drop_up,0);

txview.setCompoundDrawablesWithIntrinsicBounds(left,top,right,bottom);

回答7:

For changing left and right both at a time I use this single line.

download.setCompoundDrawablesWithIntrinsicBounds( R.drawable.ic_lock_open_white_24dp, 0, R.drawable.ic_lock_open_white_24dp, 0);

        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

et_feedback.setCompoundDrawablesWithIntrinsicBounds(0,0, 0, 0);

回答9:

If it requires android graphics drawable then this will work

Drawable dw = getApplicationContext().getResources().getDrawable(R.drawable.edit);
Button start = (Button)findViewById(R.id.buttonStart);
start.setCompoundDrawablesWithIntrinsicBounds(dw, null, null, null);
