android - 以编程方式创建的编辑文本的文本输入布局

Question

我已经在 android activity.java 文件中以编程方式创建了 edittexts。我想为编辑文本添加文本输入布局。有什么办法可以做到这一点。我已将 edittext 包装在 xml 文件中。我希望对以编程方式创建的编辑文本执行相同的操作。

提前致谢。

public class FirstFragment extends Fragment {


      EditText emailText;
      EditText passText;
      Button loginButton;
      TextView registerView;
      int counter=0;


    public FirstFragment() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {


        View view = inflater.inflate(R.layout.fragment_first, container, false);
        emailText  = (EditText) view.findViewById(R.id.emailText);
        passText = (EditText) view.findViewById(R.id.passwordText);
        loginButton = (Button) view.findViewById(R.id.LoginButton);
        registerView = (TextView) view.findViewById(R.id.RegisterView);



        final TextInputLayout nameText = new TextInputLayout(getActivity());
        final TextInputLayout DeptText = new TextInputLayout(getActivity());
        final EditText phoneNumber = new EditText(getActivity());
        final Button registerButton = new Button(getActivity());
        final LinearLayout layout = (LinearLayout)view.findViewById(R.id.fragmentLayout);
        phoneNumber.setInputType(InputType.TYPE_CLASS_PHONE);
        LinearLayout.LayoutParams parameters1 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT) ;
        nameText.setLayoutParams(parameters1);
        DeptText.setLayoutParams(parameters1);
        phoneNumber.setLayoutParams(parameters1);
        LinearLayout.LayoutParams parameters2 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT) ;
        parameters2.gravity = Gravity.CENTER;
        registerButton.setLayoutParams(parameters2);
        nameText.setHint("Enter Name");
        DeptText.setHint("Enter Department");
        phoneNumber.setHint("Enter Phone Number");
        registerButton.setText("Register");
        registerView.setTextColor(Color.BLUE);
        registerView.setTextSize(17);



        registerView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {



                counter++;
                if(counter==1) {
                    layout.addView(nameText,1 );
                    layout.addView(DeptText, 2);
                    layout.addView(phoneNumber,3);
                    layout.removeView(loginButton);
                    layout.addView(registerButton,5);
                    registerView.setText("Already signed Up? login");
                }
                else{
                    layout.removeView(nameText);
                    layout.removeView(DeptText);
                    layout.removeView(phoneNumber);
                    layout.removeView(registerButton);
                    layout.addView(loginButton,2);
                    registerView.setText("New User? Sign Up");
                    counter=0;

                }


            }
        });
     return view;
    }


}

您可以像这样从 XML 文件扩充布局:

在布局资源中创建 text_input_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.TextInputLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.design.widget.TextInputEditText
        android:inputType="phone"
        android:hint="change hint"
        android:id="@+id/text_input_edit_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</android.support.design.widget.TextInputLayout>

然后在你的代码中扩充它

TextInputLayout txtInputLayout = (TextInputLayout) LayoutInflater.from(getActivity()).inflate(R.layout.text_input_layout,null);
TextInputEditText txtInputEditText = (TextInputEditText) txtInputLayout.findViewById(R.id.text_input_edit_text);
mRoot.addView(txtInputLayout);
