This is a simple example showing how will you disable any input on your current application screen in android.
This is done by showing a transparent overlay dialog on the screen.
This is how it is done.

package pack.coderzheaven;

import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class DisableInputDemo extends Activity {

	Dialog overlayDialog;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button b = (Button)findViewById(R.id.Button01);
        b.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				disableAnyInput();
			}
		});
    }

    public void disableAnyInput(){
    	Toast.makeText(getApplicationContext(), "This will disable any input. Click the backbutton " +
    					"to enable any input.", Toast.LENGTH_LONG).show();
    	 overlayDialog = new Dialog(DisableInputDemo.this, android.R.style.Theme_Panel);
    	 overlayDialog.setCancelable(true);
         overlayDialog.show();
    }
}

The layout for the above java file- main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="How to disable any input on the screen? Coderzheaven Demo"
    />
<EditText
	android:text=""
	android:hint="Type anything"
	android:id="@+id/EditText01"
	android:layout_width="fill_parent"
	android:layout_height="wrap_content">
</EditText>
<Button
	android:text="Click me to disable any input"
	android:id="@+id/Button01"
	android:layout_width="wrap_content"
	android:layout_height="wrap_content">
</Button>
</LinearLayout>
