    copied!<p>I'm new to Android so sorry if the question is easy to answer. I have two buttons, a decrease and an increase button, and in the middle of them a TextView which displays a value.</p> <p>When I hit the decrease button, the value in the TextView decreases and increases when I hit the increase button, no problem with that, I got that working but the problem is the value only increases/decreases by 1 on a single click. What I'm trying to achieve is that as I continuously press the button (the increase button for example), the value is also continuously increasing and only stops when I release the increase button.</p> <p>Is that possible? If so, can you show some sample code or references on how to implement that? Thanks!</p> <p>Here is my main.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" &gt; &lt;RelativeLayout android:layout_width="fill_parent" android:layout_height="44dp" android:gravity="center_horizontal" &gt; &lt;Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:text="&amp;lt;" /&gt; &lt;TextView android:id="@+id/textView1" android:layout_width="50dp" android:layout_height="fill_parent" android:layout_alignBottom="@+id/button1" android:layout_toRightOf="@+id/button1" android:gravity="center" android:text="45" /&gt; &lt;Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_toRightOf="@+id/textView1" android:text="&amp;gt;" /&gt; &lt;/RelativeLayout&gt; &lt;/RelativeLayout&gt; </code></pre> <p>and here is my Main.java</p> <pre><code>import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; public class Main extends Activity { private Button _decrease; private Button _increase; private TextView _value; private static int _counter = 45; private String _stringVal; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); _decrease = (Button) findViewById(R.id.button1); _increase = (Button) findViewById(R.id.button2); _value = (TextView) findViewById(R.id.textView1); _decrease.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Log.d("src", "Decreasing value..."); _counter--; _stringVal = Integer.toString(_counter); _value.setText(_stringVal); } }); _increase.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Log.d("src", "Increasing value..."); _counter++; _stringVal = Integer.toString(_counter); _value.setText(_stringVal); } }); } } </code></pre>
