如何在对话框中创建编辑文本框

我试图在输入密码的对话框中创建一个编辑文本框。我作的时候，却不能作。我是一个初学者。请帮帮我。

public class MainActivity extends Activity {

Button create, show, setting;
//String pass="admin";String password;

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

    create = (Button)findViewById(R.id.amcreate);
    setting = (Button)findViewById(R.id.amsetting);
    show = (Button)findViewById(R.id.amshow);
    //input = (EditText)findViewById(R.id.this);

    setting.setVisibility(View.INVISIBLE);

    create.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            Intent myIntent1 = new Intent(view.getContext(), Create.class);
            startActivityForResult(myIntent1, 0);
        }

    });

    show.setOnClickListener(new View.OnClickListener() {
        //@SuppressWarnings("deprecation")
        public void onClick(final View view) {

            // Creating alert Dialog with one Button
            AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);

            //AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();

            // Setting Dialog Title
            alertDialog.setTitle("PASSWORD");

            // Setting Dialog Message
            alertDialog.setMessage("Enter Password");
            **final EditText input = new EditText(this);**
            //alertDialog.setView(input);

            // Setting Icon to Dialog
            alertDialog.setIcon(R.drawable.key);

            // Setting Positive "Yes" Button
            alertDialog.setPositiveButton("YES",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,int which) {
                            // Write your code here to execute after dialog
                            Toast.makeText(getApplicationContext(),"Password Matched", Toast.LENGTH_SHORT).show();
                            Intent myIntent1 = new Intent(view.getContext(), Show.class);
                            startActivityForResult(myIntent1, 0);
                        }
                    });
            // Setting Negative "NO" Button
            alertDialog.setNegativeButton("NO",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            // Write your code here to execute after dialog
                            dialog.cancel();
                        }
                    });

            // closed

            // Showing Alert Message
            alertDialog.show();
        }

    });

图像

我想得到as

 AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
 alertDialog.setTitle("PASSWORD");
 alertDialog.setMessage("Enter Password");

 final EditText input = new EditText(MainActivity.this);
 LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
     LinearLayout.LayoutParams.MATCH_PARENT,
     LinearLayout.LayoutParams.MATCH_PARENT);
 input.setLayoutParams(lp);
 alertDialog.setView(input);
 alertDialog.setIcon(R.drawable.key);

 alertDialog.setPositiveButton("YES",
     new DialogInterface.OnClickListener() {
         public void onClick(DialogInterface dialog, int which) {
             password = input.getText().toString();
             if (password.compareTo("") == 0) {
                 if (pass.equals(password)) {
                     Toast.makeText(getApplicationContext(),
                         "Password Matched", Toast.LENGTH_SHORT).show();
                     Intent myIntent1 = new Intent(view.getContext(),
                         Show.class);
                     startActivityForResult(myIntent1, 0);
                 } else {
                     Toast.makeText(getApplicationContext(),
                         "Wrong Password!", Toast.LENGTH_SHORT).show();
                 }
             }
         }
     });

 alertDialog.setNegativeButton("NO",
     new DialogInterface.OnClickListener() {
         public void onClick(DialogInterface dialog, int which) {
             dialog.cancel();
         }
     });

 alertDialog.show();
 }

 });

当前回答

试试下面的代码:

alert.setTitle(R.string.WtsOnYourMind);

 final EditText input = new EditText(context);
 input.setHeight(100);
 input.setWidth(340);
 input.setGravity(Gravity.LEFT);

 input.setImeOptions(EditorInfo.IME_ACTION_DONE);
 alert.setView(input);

其他回答

使用活动上下文

替换这个

  final EditText input = new EditText(this);

  final EditText input = new EditText(MainActivity.this);  
  LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
                        LinearLayout.LayoutParams.MATCH_PARENT,
                        LinearLayout.LayoutParams.MATCH_PARENT);
  input.setLayoutParams(lp);
  alertDialog.setView(input); // uncomment this line

您可以尝试下面的代码

我创建了一个这样的方法

 public void getReferDialog(OnSubmitBtnClick submitBtnClick) {
    AlertDialog.Builder alertDialog = new AlertDialog.Builder(activity);
    final View customLayout = activity.getLayoutInflater().inflate(R.layout.dilog_refer_id, null);
    alertDialog.setView(customLayout);
    AlertDialog alert = alertDialog.create();
    alert.setCancelable(false);
    alert.setCanceledOnTouchOutside(false);
    EditText editText = customLayout.findViewById(R.id.ed_refer_user_input);
    Button submitBtn = customLayout.findViewById(R.id.btn_refer_submit);
    TextView tvNo = customLayout.findViewById(R.id.tv_no_thanks);
    TextView tvBody = customLayout.findViewById(R.id.tv_title_refer_dialog_body);

    submitBtn.setOnClickListener(v -> {
        String userText = editText.getText().toString();
        if (!userText.equals("")) {
            alert.dismiss();
            submitBtnClick.onClick(userText);
        }else {
            tvBody.setTextColor(Color.RED);
        }
    });

    tvNo.setOnClickListener(v -> {
        alert.dismiss();
        submitBtnClick.onClick("skip");
    });
    alert.show();
}

这是我的dilog_refer_id.xml文件

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

        android:layout_centerHorizontal="true"
        android:layout_margin="16dp"
        android:background="@drawable/btn_bg"
        android:text="@string/submit"
        android:textColor="@color/textPrimaryColor" />

        android:padding="10dp"
        android:textColor="@color/drawer_item"
        android:textSize="14sp" />
</RelativeLayout>

我的bg_edit_text_reference .xml(可绘制)文件

    <?xml version="1.0" encoding="utf-8"?>
<shape android:shape="rectangle" xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/home_bg_extension"/>
    <corners android:radius="15dp"/>
</shape>

为获取用户输入数据创建接口

public interface OnSubmitBtnClick {
    void onClick(String referId);
}

最后都完成了，现在是时候调用onclick方法了

showPopupBtn.setOnClickListener(v -> {
        getReferDialog(new OnSubmitBtnClick() {
            @Override
            public void onClick(String referId) {
                Toast.makeText(LoginActivity.this, referId, Toast.LENGTH_SHORT).show();
            }
        });
    });

谢谢你，快乐编码!!

最简单的是。

创建对话框的xml布局文件。添加任何你想要的视图 EditText, ListView, Spinner等。膨胀这个视图并将其设置为AlertDialog

让我们首先从布局文件开始。

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

  
    <EditText
        android:id="@+id/etComments"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="top"
        android:hint="Enter comments(Optional)"
        android:inputType="textMultiLine"
        android:lines="8"
        android:maxLines="3"
        android:minLines="6"
        android:scrollbars="vertical" />

</LinearLayout>

final View view = layoutInflater.inflate(R.layout.xml_file_created_above, null);
AlertDialog alertDialog = new AlertDialog.Builder(requireContext()).create();
alertDialog.setTitle("Your Title Here");
alertDialog.setIcon("Icon id here");
alertDialog.setCancelable(false);
Constant.alertDialog.setMessage("Your Message Here");


final EditText etComments = (EditText) view.findViewById(R.id.etComments);
        
alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", new OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {

    }
});


alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, "Cancel", new OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        alertDialog.dismiss()
    }
});

       
alertDialog.setView(view);
alertDialog.show();

简化版本

final EditText taskEditText = new EditText(this);
AlertDialog dialog = new AlertDialog.Builder(this)
        .setTitle("Add a new task")
        .setMessage("What do you want to do next?")
        .setView(taskEditText)
        .setPositiveButton("Add", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                String task = String.valueOf(taskEditText.getText());
                SQLiteDatabase db = mHelper.getWritableDatabase();
                ContentValues values = new ContentValues();
                values.put(TaskContract.TaskEntry.COL_TASK_TITLE, task);
                db.insertWithOnConflict(TaskContract.TaskEntry.TABLE,
                        null,
                        values,
                        SQLiteDatabase.CONFLICT_REPLACE);
                db.close();
                updateUI();
            }
        })
        .setNegativeButton("Cancel", null)
        .create();
dialog.show();
return true;
