我很容易发现错误。我没有发现任何错误，但是我没有从editText中获取任何文本。请看下面的代码：

activity_pwd.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_root"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dp" >

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Enter PIN "
    android:textAppearance="?android:attr/textAppearanceLarge" />

<EditText
    android:id="@+id/pwdValue"
    android:layout_width="match_parent"
    android:maxLength="4"
    android:maxLines="1"
    android:inputType="numberPassword"
    android:layout_height="wrap_content">
</EditText>
</LinearLayout>

我立即打电话给 Lock（this）;* on MainActivity的 onCreate 方法 *

    public void LockImmediately(Context context) {
    if (lock_app) {
        View myview = LayoutInflater.from(context).inflate(R.layout.activity_pwd,null);
        enterPWD  = (EditText) myview.findViewById(R.id.pwdValue);

        AlertDialog alertDialog = new AlertDialog.Builder(this).setCancelable(false)
                .setView(R.layout.activity_pwd).setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        String user_text = enterPWD.getText().toString();
                        Log.d("onCreate pws", " i "+user_text);
                        if (pwd.equals(user_text)) {
                            dialog.dismiss();
                            Log.d("onCreate", "Work done");
                        } else {
                            dialog.dismiss();
                            MainActivity.this.finish();
                        }
                    }
                }).create();
        alertDialog.show();
    }
}

您可以看到上面的日志，我已将edittext值与“
i”连接起来，但未返回任何值。.我尝试清除数据，卸载应用程序，清理，构建所有内容，但始终得到相同的结果！任何帮助，将不胜感激..
