Answer 1

尝试以下XML代码。

<?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"
android:layout_height="match_parent">
<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Mobile Number"/>
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="+971"
        android:id="@+id/number"
        android:cursorVisible="false"
        android:textSize="20sp"/>
    <View
        android:layout_width="2dp"
        android:layout_height="40dp"
        android:background="@android:color/darker_gray"/>

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="Enter number"
            android:id="@+id/ed2"
            android:cursorVisible="true"
            android:layout_gravity="top"
            android:textSize="20sp">
    </EditText>
</LinearLayout>

Answer 2

在此图像中使用2个编辑框，一个用于获取前3个数字（国家代码），另一个用于获取其他数字

Answer 3

添加国家代码3位数字的示例，如+91或+61

  boolean isDeletePressed;

   edittext.setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View view, int i, KeyEvent keyEvent) {
            isDeletePressed = (i == KeyEvent.KEYCODE_DEL);
            return false;
        }
    });




 edittext.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void afterTextChanged(Editable editable) {



            if (editable.toString().length() == 3) {
                if (!isDeletePressed) {
                    edittext.setText(edittext.getText().toString() + "|");
                    edittext.setSelection(edittext.getText().toString().length());
                }
            } else if (editable.toString().length() == 4) {
                if (!(editable.toString().charAt(3) == '|')) {
                    edittext.setText(edittext.getText().toString().substring(0, 3) + "|" + edittext.getText().toString().substring(3));
                    edittext.setSelection(edittext.getText().toString().length());
                }
            }

        }
    });

Youtube Demo

public class MainActivity extends AppCompatActivity {

    Context context;
    String Crcode = "+ 971" + "|";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        context = this;

        TextView code = (TextView) findViewById(R.id.textView2);
        code.setText(Crcode);

        EditText number = (EditText) findViewById(R.id.editText);
        number.setText(" 2 877 2877");
        number.setSelection(number.getText().length());
    }
}
