I can't change InputType of EditText after I set it to TYPE_NULL

Question

I set the InputType of an EditText to TYPE_NULL with:

editText.setInputType(InputType.TYPE_NULL);

I can set it to TYPE_NULL, it works! But if I want to set InputType to something else, like TYPE_CLASS_TEXT, it doesn't work!

How can I change it dynamically in code? Like to TYPE_NULL, then to TYPE_CLASS_TEXT and to TYPE_NULL again?

// Try this one

**activity_main1.xml**
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/txtValue"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <Button
        android:id="@+id/btnClick"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Enable Input" />

</LinearLayout>

MainActivity1

public class MainActivity1 extends Activity {

    private Button btnClick;
    private TextView txtValue;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main1);

        txtValue = (TextView)findViewById(R.id.txtValue);
        btnClick = (Button)findViewById(R.id.btnClick);

        txtValue.setInputType(InputType.TYPE_NULL);
        btnClick.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                if(txtValue.getInputType()==InputType.TYPE_NULL){
                    txtValue.setInputType(InputType.TYPE_CLASS_TEXT);
                    txtValue.invalidate();
                    btnClick.setText("Disable Input");
                }else{
                    txtValue.setInputType(InputType.TYPE_NULL);
                    txtValue.invalidate();
                    btnClick.setText("Enable Input");
                }
            }
        });

    }

}
