Implementation

Pattern0 is a guy, but this time I will introduce Pattern1. I'm using TextInputLayout for clarity, but it's okay not to use it I want to customize without relying on Password Visibility Toggle! It is for people.

XML

activity_main.xml

<!--Abbreviation-->
    <!-- Pattern 1 -->
    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <!-- password -->
        <android.support.design.widget.TextInputEditText
            android:id="@+id/password"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="password"/>
    </android.support.design.widget.TextInputLayout>

    <!--Show / hide password-->
    <CheckBox
        android:id="@+id/password_visibility"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="15dp"
        android:layout_marginTop="10dp"
        android:text="Show password"/>

<!--Abbreviation-->

Activity

MainActivity.java

//Abbreviation

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextInputEditText password = (TextInputEditText)findViewById(R.id.password);

        CheckBox passwordVisibilityCheckBox = (CheckBox) findViewById(R.id.password_visibility);

        //Password switching checkbox
        passwordVisibilityCheckBox.setOnClickListener((View v) -> {

            //Save password cursor position
            int cursorPos = password.getSelectionStart();

            boolean checked = passwordVisibilityCheckBox.isChecked();
            if (checked) {
                //Password visualization
                password.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
                //Cursor position set
                password.setSelection(cursorPos);
            } else {
                //Password invisibility
                password.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
                password.setSelection(cursorPos);
            }
        });
    }
}

Yes completed!

At the end

There is a better implementation! I'm waiting for your comment! !!
