Body
<p>I'm implementing an Android app that record video. I'm trying to implement the zoom functionality but I'm not able to let it work. I haven't not found around any good code. I post the piece of code I have tried. this code is inside the OnCreate method in the Main Activity in which I'm implementing the video recording:</p> <pre><code>ImageView test = (ImageView) findViewById(R.id.zoom); test.setClickable(true); test.setOnClickListener(new OnClickListener() { public void onClick(View v) { Context context4 = getApplicationContext(); int duration = Toast.LENGTH_SHORT; Camera.Parameters parameters = mCamera.getParameters(); parameters.setZoom(parameters.getMaxZoom()); boolean Zoom = parameters.isZoomSupported(); int maxZoom = parameters.getMaxZoom(); if (parameters.isZoomSupported()) { if (zoom >=0 && zoom < parameters.getMaxZoom()) { parameters.setZoom(parameters.getZoom()+1); parameters.setZoom(zoom); mCamera.setParameters(parameters); Toast.makeText(context4, "Zoom Setted: "+parameters.getZoom(), duration).show(); } else { // zoom parameter is incorrect Toast.makeText(context4, "Zoom NOT Setted", duration).show(); } } } }); </code></pre> <p>So what I have is an image view called "zoom" that when clicked should increase the zoom of the video preview till reaching the max zoom allowed!!! This what I would like to implement in theory but nothing happen when I click the imageview....neither showing any toast! I'm testing it on a Nexus s. Someone knows how to modifiy this code in order to work or someone tried to implement in a different way? If yes how can I do? PS: The paramameter zoom is defined above as an int initialized to 1.</p>

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
