如何更改底线EditText颜色？

Question

I have an EditText in an AlertDialog and the bottom line color is not what I want, and I can't figure out how to change it.

Here is what I have so far.

AlertDialog.Builder adb = new AlertDialog.Builder(new ContextThemeWrapper(MainActivity.this, R.style.EditTextAlertDialog));
    adb.setTitle("Title");
    inputET = new EditText(this);
    inputET.setInputType(InputType.TYPE_CLASS_TEXT);
    inputET.setTextColor(getResources().getColor(android.R.color.white));
   inputET.setHighlightColor(getResources().getColor(android.R.color.white)); //This should change it, but it's not.
    adb.setView(inputET);

    adb.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

        }
    });

    adb.show();

For some weird reason that is not working, setHightlightColor should be it.

Answer 1

You can create a style for your dialog.

<style name="MyDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
        <item name="colorAccent">@color/yourEditTextColor</item>
    </style>

And then add it while creating your Dialog

AlertDialog.Builder adb = new AlertDialog.Builder(new ContextThemeWrapper(MainActivity.this, R.style.MyDialogTheme));

Answer 2

您需要为该用途设置背景色调：

inputET.setBackgroundTintList(ColorStateList.valueOf(intColorCode));

Answer 3

在xml文件下将它放入你的EditText： app:backgroundTint="@color/black"
