如何设置输入类型的密码编程EDITTEXT [英] how to set input type as password to edittext programatically

问题描述

大家好，我使用与编辑警报对话框text.So我想设置为密码到编辑文本programatically.I在谷歌已经搜索了很多输入类型，找出这两种方法：

Hi all I am using alert dialog with edit text.So I want to set input type as password to that edit text programatically.I have searched a lot in google and find out these two methods:

final EditText input = new EditText(getActivity()); 

input.setTransformationMethod(PasswordTransformationMethod.getInstance());

input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD); 

但它不是为我工作，这显示出我想要点text.what的text.But是我不know.So请建议我做taht的问题。
感谢所有提前。

public void showDialog(){

           /* Alert Dialog Code Start*/     
                AlertDialog.Builder alert = new AlertDialog.Builder(getActivity());
//              alert.setTitle("JPOP"); //Set Alert dialog title here
                alert.setMessage("              Please enter password"); //Message here

                Log.e("dialog in password ","passworddddddddddddddddd");

                // Set an EditText view to get user input 
                final EditText input = new EditText(getActivity());
//              input.setInputType(InputType.TYPE_CLASS_TEXT);
//              input.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
//              input.setTransformationMethod(PasswordTransformationMethod.getInstance());

//              final EditText input = new EditText(getActivity()); 
                input.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
                input.setTransformationMethod(new PasswordTransformationMethod());


                input.setHint("Password");
                input.setSingleLine();
                input.setTextSize(14);
                alert.setView(input);

                alert.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {

                    strPassword = input.getEditableText().toString().trim();    

                    if(strPassword.length()!=0){

                 String prestatus =DataUrls.preferences.getString("Password", "");
                 if(prestatus.equals(strPassword)){

                     if(price_reports_check){

                         price_reports_check=false;

                            ReportsFragment reportfragment = new ReportsFragment();
                            FragmentManager fragmentManager = getFragmentManager();
                            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                            fragmentTransaction.replace(R.id.details, reportfragment);
                            fragmentTransaction.commit();   
                     }else{
                        PriceListFragment pricelistfragment = new PriceListFragment();
                        FragmentManager fragmentManager = getFragmentManager();
                        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                        fragmentTransaction.replace(R.id.details, pricelistfragment);
                        fragmentTransaction.commit();
                     }

                 }else
                 {
                     showDialog();
                     Toast.makeText(getActivity(), "The password you entered is wrong", Toast.LENGTH_SHORT).show();
                 }

                    }
                    else
                    {
                        showDialog();
                        Toast.makeText(getActivity(), "Please Enter Password", Toast.LENGTH_SHORT).show();

                    }

                } // End of onClick(DialogInterface dialog, int whichButton)
            }); //End of ok....

                alert.setNegativeButton("CANCEL", new DialogInterface.OnClickListener() {
                  public void onClick(DialogInterface dialog, int whichButton) {
                    // Canceled.
                      dialog.cancel();
                  }
            }); //End of alert.setNegativeButton


                AlertDialog alertDialog = alert.create();

                   TextView title = new TextView(getActivity());
                  // You Can Customise your Title here 
                    title.setText("JPOP");
//                  title.setBackgroundColor(Color.DKGRAY);
                    title.setPadding(10, 10, 10, 10);
                    title.setGravity(Gravity.CENTER);
//                  title.setTextColor(Color.WHITE);
                    title.setTextSize(20);
                    alert.setCustomTitle(title);
                    alert.setCancelable(false);

                    alert.show();


         }

所以，请帮我我做了什么wrong.Thanks @All

So please help me what I did wrong.Thanks @All

推荐答案

您收到此问题的因为你使用 alert.setCustomTitle（职称）;

在

input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
        input.setTransformationMethod(PasswordTransformationMethod.getInstance());

这使得它的再普通型

要么改变： alert.setCustomTitle（职称）; 以 alert.setTitle （在这里你的标题）;

或如果您要使用 customeTitle

不是使用以下code

input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
input.setTransformationMethod(PasswordTransformationMethod.getInstance());
alert.setView(input);

在

alert.setCustomTitle(title);
