Show Error on the Tip of the Edit Text Android

How to show error message under EditText in TextLayoutInput in Android?

It's easy. Read the section about Floating labels for editing text in Android Design Support Library Documentation. There it says:

In addition to showing hints, you can also display an error message
below the EditText by calling setError().

how to hide set error into edit text Android

Try this,

edtUserName.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

            }

            @Override
            public void afterTextChanged(Editable s) {
                if (edtUserName.getText().toString().trim().length() > 0) {
                    usernameLayout.setError(null);

                }
            }
        });

Design Android EditText to show error message as described by google

There's no need to use a third-party library since Google introduced the TextInputLayout as part of the design-support-library.

Following a basic example:

Layout

<android.support.design.widget.TextInputLayout
    android:id="@+id/text_input_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:errorEnabled="true">

    <android.support.design.widget.TextInputEditText
        android:id="@+id/edit_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Enter your name" />

</android.support.design.widget.TextInputLayout>

Note: By setting app:errorEnabled="true" as an attribute of the TextInputLayout it won't change it's size once an error is displayed - so it basically blocks the space.

Code

In order to show the Error below the EditText you simply need to call #setError on the TextInputLayout (NOT on the child EditText):

TextInputLayout til = (TextInputLayout) findViewById(R.id.text_input_layout);
til.setError("You need to enter a name");

Result

To hide the error and reset the tint simply call til.setError(null).

Note

In order to use the TextInputLayout you have to add the following to your build.gradle dependencies:

dependencies {
    compile 'com.android.support:design:25.1.0'
}

Setting a custom color

By default the line of the EditText will be red. If you need to display a different color you can use the following code as soon as you call setError.

editText.getBackground().setColorFilter(getResources().getColor(R.color.red_500_primary), PorterDuff.Mode.SRC_ATOP);

To clear it simply call the clearColorFilter function, like this:

editText.getBackground().clearColorFilter();

Automatically show text of error in EditText

You can set focus to the EditText so that the user doesn't have to click on it.

editText.requestFocus()

However, this would still only show one error at a time. I believe this is probably still the best way to go since that's the way the platform implements it.

Android EditText error message popup text not showing

You need to use
style="@style/AppTheme.WhiteEditText"

Instead of android:theme="@style/AppTheme.WhiteColorAccent"

Now question is why need to use style Instead of android:theme

When you use style it apply will apply only to that view

and When you use android:theme it apply will apply view as well as all of its children.
