【问题描述】：

我想将导航抽屉名称和电子邮件中配置文件的外观更改为 Playstore 中的名称和电子邮件用户。这是我使用 MySQL 登录的代码：

LoginActivity.java

 @Override
                public void onResponse(String response) {
                    try {
                        JSONObject jsonObject= new JSONObject(response);
                        String success = jsonObject.getString("success");
                        JSONArray jsonArray = jsonObject.getJSONArray("login");

                        if (success.equals("1")){

                            for (int i=0; i<jsonArray.length();i++){
                                JSONObject object= jsonArray.getJSONObject(i);
                                String name = object.getString("name").trim();
                                Toast.makeText(LoginActivity.this, "Login Berhasil. \nSelamat Datang : "+name, Toast.LENGTH_SHORT).show();
                                Intent intent = new Intent(LoginActivity.this,MainActivity.class);
                                intent.putExtra("name", name);
                                intent.putExtra("email", email);
                                startActivity(intent);
                                loading.setVisibility(View.GONE);

                            }
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                        loading.setVisibility(View.GONE);
                        btnLogin.setVisibility(View.VISIBLE);
                        Toast.makeText(LoginActivity.this, "Error Check Kembali Email dan Password"+e.toString(), Toast.LENGTH_SHORT).show();
                    }
                }
            },
            new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            loading.setVisibility(View.GONE);
            btnLogin.setVisibility(View.VISIBLE);
            Toast.makeText(LoginActivity.this, "Error"+error.toString(), Toast.LENGTH_SHORT).show();
        }

我的问题只是从这个登录到在导航栏上显示名称和电子邮件的个人资料。

这是我的导航来源

Nav_drawer.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:background="@color/colorAccent"
    android:gravity="bottom"
    android:padding="16dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark"
    android:layout_height="match_parent"
    android:id="@+id/nav">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:src="@mipmap/ic_launcher_round"/>

    <TextView
        android:id="@+id/name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="8dp"
        android:text="Your Name"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"
        />
    <TextView
        android:id="@+id/email"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Your Email@gmail.com"/>
</LinearLayout>

home.java

public class MainActivity extends AppCompatActivity {
    private DrawerLayout drawer;
    private TextView name,email;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        name = findViewById(R.id.name);
        email = findViewById(R.id.email);

        Intent intent = getIntent();
        String extraName = intent.getStringExtra("name");
        String extraEmail = intent.getStringExtra("email");

        name.setText(extraName);
        email.setText(extraEmail);

        drawer = findViewById(R.id.drawer_layout);

        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawer,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close);
        drawer.addDrawerListener(toggle);
        toggle.syncState();
    }

    @Override
    public void onBackPressed() {
        if (drawer.isDrawerOpen(GravityCompat.START)){
            drawer.closeDrawer(GravityCompat.START);
        }else {
            super.onBackPressed();
        }

    }
}

【问题讨论】：

你可以像 nav.getHeaderView(0);然后更改子视图:)
所以我应该在 setContentView 之后替换 nav.getHeaderView？好的，我先试试

【解决方案1】：

您必须首先获取标题视图，然后您需要获取您感兴趣的子视图，然后才能设置文本，例如

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //... other onCreate setup        

        NavigationView mNavigationView = findViewById(R.id.nav_view);               
        View headerView = mNavigationView.getHeaderView(0);
        // get user name and email textViews
        TextView userName = headerView.findViewById(R.id.text_user_name);
        TextView userEmail = headerView.findViewById(R.id.text_email_address);
        // set user name and email
        userName.setText("username");
        userEmail.setText("email.user@domain.com");

}
