Android realizes the function of calling system camera to take pictures and video _android

This article implements the Android system camera call to take photos

The layout of the project is fairly simple, with only one button:

<relativelayout xmlns:android= "http://schemas.android.com/apk/res/android"
  xmlns:tools= "http:// Schemas.android.com/tools "
  android:layout_width=" match_parent "
  android:layout_height=" Match_parent "
  tools:context= ". Mainactivity ">

  <button
    android:onclick=" click "
    android:layout_width=" Wrap_content
    " android:layout_height= "Wrap_content"
    android:layout_centerhorizontal= "true"
    android:layout_ Centervertical= "true"
    android:text= "call system camera Photo"/>

</RelativeLayout>

First open the list file under the Packages\apps\camera folder and find the following code:

 <activity android:name= "Com.android.camera.Camera" android:configchanges= "Orientation|keyboardhidden" Android:theme= "@android: Style/theme.black.notitlebar.fullscreen" android:screenorientation= "Landscape" an
        Droid:cleartaskonlaunch= "true" android:taskaffinity= "Android.task.camera" > <intent-filter> <action android:name= "Android.intent.action.MAIN"/> <category android:name= "Android.intent.category.DEFA" ULT "/> <category android:name= Android.intent.category.LAUNCHER"/> </intent-filter> & lt;intent-filter> <action android:name= "Android.media.action.IMAGE_CAPTURE"/> <category Id:name= "Android.intent.category.DEFAULT"/> </intent-filter> <intent-filter> <actio n android:name= "Android.media.action.STILL_IMAGE_CAMERA"/> <category android:name= "Android.intent.category". DEFAULT "/>;/intent-filter> </activity>
 

The relevant code is as follows:

public class Mainactivity extends activity {

  @Override
  protected void onCreate (Bundle savedinstancestate) {
    super.oncreate (savedinstancestate);
    Setcontentview (R.layout.activity_main);
  }

  public void Click (View view) {
    *
     * * <intent-filter> <action
     * android:name= Android.media.action.IMAGE_CAPTURE "/> <category
     * android:name=" Android.intent.category.DEFAULT "/> </intent-filter>//
    Activate the camera for the system to take photos
    intent intent = new intent ();
    Intent.setaction ("Android.media.action.IMAGE_CAPTURE");
    Intent.addcategory ("Android.intent.category.DEFAULT");
    
    Saves the photo to the specified path
    file = new file ("/sdcard/image.jpg");
    Uri uri = uri.fromfile (file);
    Intent.putextra (Mediastore.extra_output, URI);
    
    StartActivity (intent);

  }

The relevant code to activate the video function is also simple:

public class Mainactivity extends activity {@Override protected void onCreate (Bundle savedinstancestate) {Supe
    R.oncreate (savedinstancestate);
  Setcontentview (R.layout.activity_main); public void Click (View view) {/* <intent-filter> <action * android:name=) android.media.acti On.
     Video_capture "/> <category * android:name=" Android.intent.category.DEFAULT "/> </intent-filter>
    *///Activate the camera of the system for video Intent Intent = new Intent ();
    Intent.setaction ("Android.media.action.VIDEO_CAPTURE");

    Intent.addcategory ("Android.intent.category.DEFAULT");
    Save the video to the specified path file = new file ("/sdcard/video.3pg");
    Uri uri = uri.fromfile (file);

    Intent.putextra (Mediastore.extra_output, URI);
  Startactivityforresult (Intent, 0); @Override protected void Onactivityresult (int requestcode, int resultcode, Intent data) {Toast.maketext (this
    , "Call camera Complete", 0. Show (); Super.onactivityresult (Requestcode, ResultCode, data);

 }

}
