带有EditText的自定义AlertDialog

Question

我尝试开发一个小android应用程序，并显示一个对话框警报，其中只包含一个edittext，以填充自定义内容作为下一个链接

创建自定义布局我有这个代码，但它不工作

public class TraceDialogFragment extends DialogFragment {


TraceDialogListener mListener;

public interface TraceDialogListener {
    public void onDialogPositiveClick(DialogFragment dialog);
    public void onDialogNegativeClick(DialogFragment dialog);
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    // Get the layout inflater
    LayoutInflater inflater = getActivity().getLayoutInflater();


    builder.setView(inflater.inflate(R.layout.activity_trace, null))
            .setIcon(R.drawable.ic_action_locate)
            .setTitle(R.string.trace_title)
            // Add action buttons
            .setPositiveButton(R.string.btn_ok, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int id) {
                    mListener.onDialogPositiveClick(TraceDialogFragment.this);
                }
            })
            .setNegativeButton(R.string.btn_cancel, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    mListener.onDialogNegativeClick(TraceDialogFragment.this);
                }
            });
    return builder.create();
}

@Override
public void onAttach(Context context) {
    super.onAttach(context);

    try{
        mListener = (TraceDialogListener) context;
    }catch (ClassCastException e){
        throw new ClassCastException(context.toString() + " must implement TraceDialogListener");
    }
}

}

但是代码循环运行

LayoutInflater inflater = getActivity().getLayoutInflater();

我不明白

在我班上的主要活动

我有这个密码

class MainActivity extends AppCompatActivity implements TraceDialogFragment.TraceDialogListener

DialogFragment traceDialog = new TraceDialogFragment();
traceDialog.show(getSupportFragmentManager(),"TraceDialogFragment");

这是我的风格。xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

</resources>

我的logcat是下一个

                                                                                                at android.support.v7.app.AppCompatDelegateImplV9.createSubDecor(AppCompatDelegateImplV9.java:359)

谢谢你的帮助，

Answer 1

我通过更改名称空间来解决问题

导入android.support.v7.app.AlertDialog；导入android.app.AlertDialog；

我不是什么都懂。。。。但它是有效的

只需在活动或Oncreate或OnCreateView中的片段中调用此方法

 public void inflateDialogue() {
    LayoutInflater layoutInflater=SelectUsers.this.getLayoutInflater();
    final View view = layoutInflater.inflate(R.layout.dialog_group_name, null);
    AlertDialog alertDialog = new AlertDialog.Builder(this).create();
    alertDialog.setTitle("Group_name");

    alertDialog.setCancelable(false);

    edt_groupName = (EditText) view.findViewById(R.id.edt_groupName);

    alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, getResources().getString(R.string.ok), new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            str_getTextFrom=edt_groupName.getText().toString();
            //here we have to call Database firebase

            dialog.dismiss();

        }
    });
    alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, getResources().getString(R.string.cancel), new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });
    alertDialog.setView(view);
    alertDialog.show();
}

在xml

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout 
  xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
