Android之在launcher里面动态加载桌面图标
1、在手机桌面加载图标方式
1)、动态加载
Launcher.java
private void addSourceList() {
Intent launchIntent = new Intent(this, RcGrpActivity.class);
launchIntent.setAction(Intent.ACTION_MAIN);
launchIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Intent addIntent = new Intent();
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, launchIntent);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.source_list));
addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
ShortcutIconResource.fromContext(this, R.drawable.keycard));
ShortcutInfo shortcut = mModel.infoFromShortcutIntent(this, addIntent);
shortcut.deletable = false;
shortcut.titleResource = getResources().getResourceName(R.string.source_list);
shortcut.presetItemId = getResources().getInteger(R.integer.preset_source_list_icon);
if (LauncherModel.presetItemExists(this, shortcut.presetItemId)) {
return;
}
ArrayList<ItemInfo> list = new ArrayList<ItemInfo>();
list.add(shortcut);
mModel.addAndBindAddedApps(this, list, new ArrayList<AppInfo>(), true);
}
LauncherModel.java
static boolean presetItemExists(Context context, int presetItemId) {
final ContentResolver cr = context.getContentResolver();
Cursor c = cr.query(LauncherSettings.Favorites.CONTENT_URI,
new String[]{"title"},
"presetItemId=?",
new String[]{Integer.toString(presetItemId)},
null);
if (c == null) {
return false;
}
try {
return c.moveToFirst();
} finally {
c.close();
}
}
优点:不需要平板适配
2)、静态加载
通过xml文件加载
1、xml文件
<?xml version="1.0" encoding="utf-8"?>
<favorites xmlns:launcher="http://schemas.android.com/apk/res-auto">
<shortcut
launcher:uri="#Intent;action=com.sangfor.action.ACTION_OPEN_RESOURCE;category=android.intent.category.DEFAULT;end"
launcher:iconRes="@drawable/ic_setting_app"
launcher:titleRes="@string/source_list"
launcher:container="-100"
launcher:screen="0"
launcher:x="2"
launcher:y="2"
launcher:deletable="false"
launcher:presetItemId="@integer/preset_settings_icon"
/>
</favorites>
2、 AndroidManifest.xml
<activity
android:name="com.sangfor.vpn.client.phone.resource.RcGrpActivity"
android:configChanges="orientation|keyboardHidden|screenSize"
android:label="@string/about"
android:screenOrientation="behind"
android:theme="@android:style/Theme.Light.NoTitleBar" >
<intent-filter>
<action android:name="com.sangfor.action.ACTION_OPEN_RESOURCE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
