Two ways to intercept Android images

This article mainly provides the image interception and image selection interception of the Android system, which is applicable to the environment of the app Avatar selection.

Photo interception

Turn on the camera

Intent Intent = new Intent (Mediastore. Action_image_capture); Startactivityforresult (Intent, "custom");

Intent Intent = getcropimageintent (data); Startactivityforresult (Intent, "custom");

Process the acquired picture

Public Static Intent getcropimageintent (Bitmap data) { Intent Intent = new Intent ("Com.android.camera.action.CROP"); Intent.settype ("image/*"); Intent.putextra ("Data", data); Intent.putextra ("crop", "true"); Intent.putextra ("Aspectx", 1); Intent.putextra ("Aspecty", 1); // Intent.putextra ("Outputx"); // Intent.putextra ("Outputy"); Intent.putextra ("Return-data", true); Intent.putextra ("OutputFormat", "JPEG"); return Intent; }

Get Data

@Override protected void onactivityresult (int requestcode, int resultcode, Intent data) { //  TODO auto-generated Method Stub Switch (Requestcode) { // xxxxx Bitmap photo = Data.getparcelableextra ("Data"); } }

Select Intercept

Key code

Intent innerintent = new Intent (Intent. Action_get_content); Innerintent.putextra ("crop", "true"); //Clip box Innerintent.putextra ("Aspectx", 1); //Zoom in and Zoom out Innerintent.putextra ("aspectY", 1); //  if Aspectx and the Aspect if Y is set to the same value at the same time, the rectangle Innerintent.settype ("image/*"); //view type detail type in Com.google.android.mms.ContentType tempfile=new File ("/sdcard/"+calendar.getinstance (). Gettimeinmillis () +". jpg" ); //In time seconds for file name File temp = new file ("/sdcard/"); //Directory Files folder, if it does not exist, create    if (!temp.exists ()) { Temp.mkdir (); } Innerintent.putextra ("Output", Uri.fromfile (tempfile)); //Incoming target file Innerintent.putextra ("OutputFormat", "JPEG"); //File format Intent wrapperintent = Intent.createchooser (innerintent, "Select Picture First"); //Start and set the title Startactivityforresult (wrapperintent, 1); //Set return code to 1 with Onactivityresult

//Call succeeded back method @Override protected void onactivityresult (int requestcode, int resultcode, Intent data) { Super. Onactivityresult (Requestcode, ResultCode, data); Switch (Requestcode) { Case 1: //         processing logic here break; } }
