Android Camera变焦编程步骤
1、添加Camera权限
2、判断是否支持变焦
publicbooleanisSupportZoom()
{
booleanisSuppport=true;
if(mCamera.getParameters().isSmoothZoomSupported())
{
isSuppport=false;
}
returnisSuppport;
}
3、修改焦距
publicvoidsetZoom()
{
if(mIsSupportZoom)
{
try
{
Parametersparams=mCamera.getParameters();
finalintMAX=params.getMaxZoom();
if(MAX==0)return;
intzoomValue=params.getZoom(); Trace.Log("-----------------MAX:"+MAX+" params:"+zoomValue); zoomValue+=5; params.setZoom(zoomValue); mCamera.setParameters(params); Trace.Log("IssupportZoom"+params.isZoomSupported()); } catch(Exceptione) { Trace.Log("--------exceptionzoom"); e.printStackTrace(); } } else { Trace.Log("--------thephonenotsupportzoom"); } }
