InputMethodHolder

A keyboard listener for Android which by hooking the InputMethodManager. Of course you can also hook the other system services similarly, If you want, create a class, make it a subclass of Hook, and using ServiceManagerHook to hook ServiceManager, learn more from InputMethodManagerHook. If you like this project, ,welcome to fork or star!

Steps：

1.Import InputMethodHodler as a library
2.Call the initialization method, the method will hook InputMethodManager, recommended to call at attachBaseContext:

public class MyApplication extends Application {
    @Override
    protected void attachBaseContext(Context base) {
        InputMethodHolder.init(base);
        super.attachBaseContext(base);
    }
}

3.Register the listener,and unregister when unused：

onInputMethodListener = new OnInputMethodListener() {
    @Override
	public void onShow(boolean result) {
	    Toast.makeText(MainActivity.this, "Show input method! " + result, Toast.LENGTH_SHORT).show();
	}
	@Override
	public void onHide(boolean result) {
	    Toast.makeText(MainActivity.this, "Hide input method! " + result, Toast.LENGTH_SHORT).show();
	}
};
InputMethodHolder.registerListener(onInputMethodListener);

@Override
protected void onDestroy() {
    super.onDestroy();
    InputMethodHolder.unregisterListener(onInputMethodListener);
}

4.Don't forget to release when exiting(avoid memory leaks)：

InputMethodHolder.release();

Please read Sample for getting specific use, and if have any problems please submit ISSUE.

Defect

onShow works well in most situations, but onHide can only give callbacks by calling hideSoftInputFromWindows manually. The reason is that system keyboard is hold by another process, and the procedure for using the keyboard by an application is a local process remote call through InputMethodManager, the hook is just that InputMethodManager of the application's process.

public interface OnInputMethodListener {
    void onShow(boolean result);
    void onHide(boolean result);
}
