how to make hint disappear when edittext is touched?

Question

In my application in android are many EditText fields. And I ran into a problem with hint. It is not disappearing when EditText is focused, but it disappears when I start to

Answer 1

You can also custom your XML code by using Selector. Here is an example code.

Create a selector. In file selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:color="@android:color/transparent" />
    <item android:color="@color/gray" />
</selector>

In your view

android:textColorHint="@drawable/selector"

Answer 2

The way I like to do it (now in Kotlin) is to have the hint reappear if the user clicks elsewhere. Initialize the hint-string outside of your class, also importing your synthetic layout there:

import kotlinx.android.synthetic.main.activity_layout.*
private const val MY_HINT= "The Hint Shown"

Then use an OnFocusChange listener:

    myEditText.setOnFocusChangeListener() { v, event ->
        myEditText.hint = if(myEditText.hasFocus()) "" else MY_HINT
        false
    }

That way the hint doesn't get lost as the user clicks around. Or, just set it to an empty string if you don't care about that!

This is my solution:

final EditText editText = (EditText) findViewById(R.id.activity_edittext);
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {
            editText .setHint("my little hint");
        } else {
            editText .setHint("");
        }
    }
});

My solution is like this. It shows hint when empty and not focused and hides if there is text or if it is touched

fun hideHint() {
        tilFloating.isHintAnimationEnabled = false
        etFloating.onFocusChangeListener = OnFocusChangeListener { v, hasFocus ->
            if ((etFloating.text != null && etFloating.text.toString() != "") || hasFocus)
                tilFloating.hint = ""
            else
                tilFloating.hint = mHint
        }
    }

Answer 5

Here's my solution, where the hint disappear when user focus editText and appears again when focus changes to other place if the edittext is still empty:

editText.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        editText.setHint("");
        return false;
    }
});

editText.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (!hasFocus) {
            editText.setHint("Hint");
        }
    }
});

hope this helps someone

findViewById(R.id.mainLayout).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                hideKeyboard();
                editText.clearFocus();
                if (TextUtils.isEmpty(editText.getText().toString())) {
                    editText.setHint("your hint");
                }
            }
        });

        editText.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                editText.setHint("");
                return false;
            }
        });


        editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus)
                    editText.setHint("");
                else
                    editText.setHint("your hint");
            }
        });
