如何在AlertDialog中输入纯文本输入？

public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setTitle("Enter The Subject Name");
    builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getActivity(), "Canceled", Toast.LENGTH_SHORT).show();
        }
    });
    builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getActivity(), "Subject Added", Toast.LENGTH_SHORT).show();
        }
    });
    Dialog dialog = builder.create();
    return dialog;
}

Answer 1

您正在寻找的是AlertDialog.Builder的setView方法。您可以创建包含edittext的xml布局，然后将其设置为对话框的视图：

<EditText
    android:id="@+id/myEditText"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginLeft="@dimen/activity_horizontal_margin"
    android:layout_marginRight="@dimen/activity_horizontal_margin"/>

然后你可以使用

final View customLayout = getActivity().getLayoutInflater().inflate(R.layout.edittext, null);
builder.setView(customLayout);

Dialog dialog = builder.create();
EditText editText = (EditText) customLayout.findViewById(R.id.myEditText);
editText.setText("Editable text");

exitByBackKey(); // call in main class

//Custom Dialog Java file
public void exitByBackKey() {

        tableDialog = new Dialog(DashBoardActivity.this);
        tableDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        tableDialog.setContentView(R.layout.exit_dialog);
        tableDialog.setCanceledOnTouchOutside(false);
        WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
        Window window = tableDialog.getWindow();
        lp.copyFrom(window.getAttributes());
        lp.width = WindowManager.LayoutParams.WRAP_CONTENT;
        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
        window.setAttributes(lp);

        tableDialog.getWindow().setGravity(Gravity.CENTER);
        tableDialog.setCancelable(true);
        tableDialog.show();
    enter code here
        CustomTextView txtMessage = (CustomTextView) tableDialog
                .findViewById(R.id.txtMessage);
        `enter code here`CustomButton btnDialogOk = (CustomButton) tableDialog
                .findViewById(R.id.btnAlertOk);
        CustomButton btnDialogcancel = (CustomButton) tableDialog
                .findViewById(R.id.btnAlertCancel);
        txtMessage.setText("Do you want to stop this Application?");
        btnDialogOk.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                tableDialog.dismiss();
                DashBoardActivity.this.finish();
            }
        });
        btnDialogcancel.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                tableDialog.dismiss();

            }
        });
    }
