如何从键盘列表中打开一个activity?
How to open an activity from the keyboard list?
我正在开发自定义键盘,想添加一个首选项页面。
我注意到 gboard 能够从 android 设置中的虚拟键盘列表中打开其首选项活动。
我也试过这样做,但我找不到任何关于如何做的信息。我试图搜索意图,但没有找到。
你有什么想法吗?

您是否在应用程序列表中获取软件包名称?
如果没有,您可以使用此键盘应用程序列表代码
InputMethodManager imeManager =
(InputMethodManager) getApplicationContext()
.getSystemService(Context.INPUT_METHOD_SERVICE);
//Keyboard application packages
List<InputMethodInfo> inputMethods = imeManager.getInputMethodList();
for (int i = 0; i < inputMethods.size(); i++) {
InputMethodInfo im = inputMethods.get(i);
String packageName = im.getPackageName();
//Getting package info
try {
PackageInfo pi = getPackageManager().getPackageInfo(packageName, PackageManager.GET_META_DATA);
String appname = pi.applicationInfo.loadLabel(getPackageManager()).toString();
String pname = pi.packageName;
String versionName = pi.versionName;
int versionCode = pi.versionCode;
Drawable icon = pi.applicationInfo.loadIcon(getPackageManager());
Log.e("InputMethods", "appname: "+appname);
Log.e("InputMethods", "pname: "+pname);
Log.e("InputMethods", "versionName: "+versionName);
Log.e("InputMethods", "versionCode: "+versionCode);
Log.e("InputMethods", "icon: "+icon);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
}
按包名启动应用程序..
Intent launchIntent = getPackageManager().getLaunchIntentForPackage("package_name");
//null pointer check in case package name was not found
if (launchIntent != null) {
startActivity(launchIntent);
}
我发现设置显示缺少什么。
您需要添加属性
android:settingsActivity="com.example.package.PreferencesActivity"
在您的 method.xml 标签内
<input-method>
