android – 检测是否已选择输入法

在我的应用程序中,我需要让用户选择一个输入法.一旦它被选中,我应该执行一些任务.如何检测到用户实际选择了InputMethod？

这是用于显示InputMethod列表的代码.

InputMethodManager imeManager = (InputMethodManager) mw.getApplicationContext().getSystemService(Context.INPUT_METHOD_SERVICE);
if (imeManager != null) {
    imeManager.showInputMethodPicker();
} else {
    Toast.makeText(mw.getApplicationContext(), "IME ERROR",
    Toast.LENGTH_LONG).show();
}

解决方法:

遗憾的是,您无法捕获用户在InputMethodPicker中选择的输入法.

但是,您可以在用户选择后使用BroadcastReceiver进行检查.
当IME更改时,将广播Intent.ACTION_INPUT_METHOD_CHANGED.

public class InputMethodChangeReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals(Intent.ACTION_INPUT_METHOD_CHANGED)) {
            .....
            /* You can check the package name of current IME here.*/
        }
    }
}

然后,注册它.

IntentFilter filter = new IntentFilter(Intent.ACTION_INPUT_METHOD_CHANGED);
registerReceiver(mReceiver, filter);
