五、搭建个人界面（待扩展）

1.以TwoFragment构建个人界面，先进行UI布局。

fragment_two.xml 

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    app:layout_constraintGuide_percent="0.95">

    <ImageView
        android:id="@+id/imageView7"
        android:layout_width="108dp"
        android:layout_height="104dp"
        android:background="@drawable/img_5"
        app:layout_constraintBottom_toTopOf="@+id/guideline12"
        app:layout_constraintEnd_toStartOf="@+id/textView4"
        app:layout_constraintHorizontal_bias="0.62"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="@+id/guideline8"
        app:layout_constraintVertical_bias="0.0" />

    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/guideline8"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.05" />

    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/guideline10"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:layout_constraintGuide_begin="20dp"
        app:layout_constraintGuide_percent=".95" />

    <TextView
        android:id="@+id/textView4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/blank"
        android:textSize="24sp"
        app:layout_constraintBottom_toTopOf="@+id/guideline12"
        app:layout_constraintEnd_toStartOf="@+id/guideline10"
        app:layout_constraintHorizontal_bias="0.59"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="@+id/guideline8"
        app:layout_constraintVertical_bias="0.4" />

    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/guideline12"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.2" />

    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/guideline13"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.6" />

    <Button
        android:id="@+id/button4"
        android:layout_width="400dp"
        android:layout_height="60dp"
        android:background="@color/white"
        android:backgroundTint="@color/transparent"
        android:text="@string/setting"
        android:textSize="24sp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="@+id/guideline13"
        app:layout_constraintVertical_bias="0.0" />

    <ImageView
        android:id="@+id/imageView9"
        android:layout_width="50dp"
        android:layout_height="50dp"
        app:layout_constraintBottom_toBottomOf="@+id/button4"
        app:layout_constraintEnd_toEndOf="@+id/button4"
        app:layout_constraintHorizontal_bias="0.05"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="@+id/guideline13"
        app:layout_constraintVertical_bias="0.5"
        app:srcCompat="@drawable/ic_baseline_settings_24" />

    <ImageView
        android:id="@+id/imageView10"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="@+id/button4"
        app:layout_constraintEnd_toEndOf="@+id/button4"
        app:layout_constraintHorizontal_bias="0.9"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="@+id/guideline13"
        app:srcCompat="@drawable/ic_baseline_keyboard_arrow_right_24" />

</androidx.constraintlayout.widget.ConstraintLayout>

其中，需要添加的矢量图有：

@drawable/ic_baseline_keyboard_arrow_right_24
@drawable/ic_baseline_settings_24

（2）编辑TwoFragment 的代码。

package com.example.peachdictionary;


import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;
import androidx.navigation.NavController;
import androidx.navigation.Navigation;

import java.util.Random;


public class TwoFragment extends Fragment {

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_two, container, false);
        return view;
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);


        TextView textView = getView().findViewById(R.id.textView4);
        Random random = new Random();
        textView.setText("用户" + random.nextInt(1000));


    }
}

（3）将Bottom Navigation Activity自带的HomeFragment（即第二个模板fragment）清空，否则会把模板覆盖在TwoFragment上。
