我实现了一个对话框，要求用户输入 PIN 以确保安全，该对话框在应用程序运行时显示，但键盘显示qwerty 键盘，但在 xml 中我设置了inputType="numberpassword"并且在 quetry 中按下任何键都不会在 EditText 中进行任何输入。但是在最小化应用程序并再次打开后，它将显示一个数字键盘，当应用程序开始时我需要显示它。
可能是哪个问题？？下面我粘贴了代码和截图。
开始
protected void onStart() {
super.onStart();
SharedPreferences SP = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
lock_app = SP.getBoolean("lock_app", false);
LockImmediately(this);
}
public void LockImmediately(Context context) {
if (lock_app) {
final View myview = LayoutInflater.from(context).inflate(R.layout.activity_pwd, null);
enterPWD = (EditText) myview.findViewById(R.id.pwdValue);
Log.d("myerror", pwd);
AlertDialog alertDialog = new AlertDialog.Builder(context).setIcon(R.drawable.ic_lock_black_24dp).setCancelable(false)
.setView(myview).setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String user_text = enterPWD.getText().toString();
if ((pwd.equals(user_text))) {
dialog.dismiss();
} else {
dialog.dismiss();
MainActivity.this.finish();
}
}
}).create();
alertDialog.show();
}
}
@Override
protected void onPause() {
super.onPause();
if (bottom_addView!=null){
bottom_addView.pause();
}
}
