copied!<p>I am programming an app in Android, where I obtain the data from the microphone, it works fine, I am able to save the amplitude of the sound. And I can update the progresssbar.</p> <pre><code> barraThread = new Thread(new Runnable() { public void run(){ while (isRecording){ actualizarBarra(getAmplitud()); //lector.setText(String.valueOf(getAmplitud())); } } },"barra Thread"); </code></pre> <p>-Where: actualizarBarra(getAmplitud()); update the value of the progressbar with the actual amplitude.</p> <p>My problems is that if I try to update a textView from that point, I get the error (</p> <blockquote> <p>“Only the original thread that created a view hierarchy can touch its views.”</p> </blockquote> <p>So I tried to update the textView using a "Handler" and also using "runOnUiThread(new Runnable() {..." but the app runs very slow and sometime crash. Do you know any way to update the progressbar and the textview at the same time, in a properly way?,</p> <h2>Thanks a lot</h2> <p>Using the the runOnUiThread solution.</p> <pre><code>private void actualizarInterfaz() { runOnUiThread(new Runnable() { @Override public void run() { actualizarBarra(getAmplitud()); lector.setText(String.valueOf(getAmplitud())); } }); } </code></pre> <p>and then in a loop: </p> <pre><code> while(isRecording){ actualizarInterfaz(); } </code></pre> <p>Was no error, just the app get frozen, so I can not see any log at the LogCat, just like is running normally but in fact does not. Thanks</p>
