Magnet
This library enables you to create a window icon similar to Facebooks chat icon, and also similar to the Link Bubble app. See the demo project for sample implementations.
Sample play store app:
The library takes care of all the touching and dragging of the window icon, leaving you with callbacks so you can save your time to implement your app.
Usage (gradle)
Via maven central
<dependency>
<groupId>com.premnirmal.magnet</groupId>
<artifactId>library</artifactId>
<version>1.2.7</version>
<type>aar</type>
</dependency>Add the following to your build.gradle
compile 'com.premnirmal.magnet:library:1.2.7'
compile 'com.facebook.rebound:rebound:0.3.8'
compile 'com.tumblr:backboard:0.1.2'How to create a Magnet
Use the required permission
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>Android api level 23+
Request the permission at runtime in your activity, before calling Magnet#show():
void checkDrawOverlayPermission() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!Settings.canDrawOverlays(this)) {
final Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, REQUEST_CODE);
} else {
// continue here - permission was granted
}
} else {
// continue here - permission was granted
}
}
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE) {
if (Settings.canDrawOverlays(this)) {
// continue here - permission was granted
}
}
}Use the magnet builder in your Activity or Service
final ImageView iconView = new ImageView(this);
iconView.setImageResource(R.drawable.ic_launcher);
final Magnet magnet = Magnet.newBuilder(this)
// a view is required
.setIconView(iconView)
// all the parameters below are optional
.setIconCallback(this)
.setHideFactor(0.2f)
.setShouldShowRemoveView(true)
.setRemoveIconShouldBeResponsive(true)
.setRemoveIconResId(R.drawable.ic_close)
.setRemoveIconShadow(R.drawable.bottom_shadow)
.setShouldStickToWall(true)
.setRemoveIconShouldBeResponsive(true)
.setInitialPosition(300, 400)
.withSpringConfig(springConfig)
.build();
magnet.show();
...
magnet.setPosition(200, 800); // to manually move the magnet
...
magnet.goToWall(); // to stick the magnet to the wall (only works if shouldStickToXWall or shouldStickToYWall is enabled)
...
magnet.destroy(); // to remove the magnetSubclassing
Instantiate your subclass of Magnet using the Builder
final MyMagnet magnet = new Magnet.Builder<MyMagnet>(MyMagnet.class, context)
.setIconView(iconView)
.build();Use the callbacks per your needs
@Override public void onFlingAway() {
Log.i(TAG, "onFlingAway");
}
@Override public void onMove(float x, float y) {
Log.i(TAG, "onMove(" + x + "," + y + ")");
}
@Override public void onIconClick(View icon, float iconXPose, float iconYPose) {
Log.i(TAG, "onIconClick(..)");
}
@Override public void onIconDestroyed() {
Log.i(TAG, "onIconDestroyed()");
