Android 无法从ActionBar按钮上的EditText获取文本单击

我在我的应用程序中使用了ActionBar。我想从EditText（即其他版面）中获取值。我已经尝试获取该布局，然后获取EditText值

获取编辑文本所在布局的代码

public View textInputChecks() {

    LayoutInflater mLayoutInflater = getLayoutInflater();
    View textQrView = mLayoutInflater.inflate(R.layout.text_qr, null);
    return textQrView;
}

点击ActionBar按钮的代码

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    // TODO This is really needed to make app icon a toggle of nav drawer.
    if (mDrawerToggle.onOptionsItemSelected(item)) {
        return true;
    } else {

        switch (item.getItemId()) {

        case R.id.action_ok:
            View textInputView = textInputChecks();
            EditText textInput = (EditText) textInputView.findViewById(R.id.qrTextInput);
            String text = textInput.getText().toString();
            if (text.length()>0) {
                Toast.makeText(getApplicationContext(), "Ok",
                        Toast.LENGTH_LONG).show();
            } else {
                Toast.makeText(getApplicationContext(), "No Text added",
                        Toast.LENGTH_LONG).show();
            }
            break;

        default:
            break;
        }
    }
    return super.onOptionsItemSelected(item);
}

即使将文本添加到

ViewGroup
Change
View
，它也始终显示“No Text Added”Toast消息，因为
textInputChecks
函数在ViewGroup textQrView=mLayoutInflater.flate（R.layout.Text\u qr，null）中显示空值错误；您是否也播放了
视图组
？并尝试
LayoutInflater充气器=（LayoutInflater）context.getSystemService（context.LAYOUT\u充气器\u服务）取而代之的是，您的充气机仍保持不变。无错误且未获取文本您是否也更改了
View textInputView=textInputChecks（）到视图组？
