键盘不会出现在Android自定义对话框中

键盘不会出现在自定义对话框中。 我尝试了以下各种方法，但没有成功

passwdDialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
passwdDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
edtTitle.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
imm.showSoftInput(edtTitle, 0);

有没有办法在自定义对话框的

EditText

中使用键盘

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final PasswdDialog passwdDialog = new PasswdDialog(MainActivity.this);
        passwdDialog.setCanceledOnTouchOutside(false);
        passwdDialog.show();

        Button btnConfirm = passwdDialog.findViewById(R.id.btn_confirm);
        Button btnCancel = passwdDialog.findViewById(R.id.btn_cancel);
        final EditText edtTitle = passwdDialog.findViewById(R.id.edt_title);
    }
}

public class PasswdDialog extends Dialog
{
    private Context context;

    public PasswdDialog(Context context) {
        super(context);
        this.context = context;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_passwd);
        getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        EditText edtTitle = findViewById(R.id.edt_title);
    }
}

布局有可能是错的吗

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"

如果您想在打开自定义对话框时显示键盘，如下图所示

InputMethodManager ime = null;

ime = (InputMethodManager)Category_Edit.this.getSystemService(Context.INPUT_METHOD_SERVICE);

ime.showSoftInputFromInputMethod(((EditText)dialog.findViewById(R.id.edt)).getWindowToken(), InputMethodManager.SHOW_FORCED);
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

尝试在editText xml文件中添加以下代码

android:selectAllOnFocus="true"

更新：其他方式 在对话框中添加lisener怎么样

passwdDialog.setOnShowListener(new DialogInterface.OnShowListener() {

            @Override

            public void onShow(DialogInterface dialog) {

                InputMethodManager imm = (InputMethodManager)                                      mContext.getSystemService(Context.INPUT_METHOD_SERVICE);

                imm.showSoftInput(mFullPopUpEditBox, 0);

            }

        });

非常感谢您的回答，但它仍然不起作用。不仅在某些平板电脑上，而且在其他设备上，我认为这是平板电脑的问题。非常感谢你。
