[英]OnClick item in NavigationDrawer in Android Studio
我知道这很常见，但我真的很困惑如何将 onClickListener 应用于我的 navigationDrawer 项目，我有两个项目，即编辑配置文件和注销我只想Toast或打印，如果其中一个被选中，有没有人可以帮帮我，我已经在互联网上搜索了，但我没有找到 OnClickListener，需要帮助
我认为我的MainActivity缺少onCreate()
OnCreate() 主活动
setContentView(R.layout.dashboard_main);
DrawerLayout drawerLayout = findViewById(R.id.drawerlayout);
NavigationView navigationView = (NavigationView) findViewById(R.id.navigationview);

更新后我尝试了下面的代码，但是当我单击项目时，它会自动隐藏侧边栏并且没有Toast弹出
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem item) {
if (item.getItemId() == R.id.editProfile)
{
Toast.makeText(getApplicationContext(),"profile",Toast.LENGTH_SHORT).show();
}
else if (item.getItemId() == R.id.logout_menu)
{
Toast.makeText(getApplicationContext(),"logout",Toast.LENGTH_SHORT).show();
}
return false;
}
});
首先，您需要在 Activity 上实现 NavigationView.OnNavigationItemSelectedListener 接口。
然后在你的 onCreate() 方法上输入 navigationView.setNavigationItemSelectedListener(this); 在此之后覆盖方法 onNavigationItemSelected。
在这里你可以使用这个示例代码。
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
if (item.getItemId() == R.id.editProfile)
{
//edit your profile
}
else if (item.getItemId() == R.id.logout)
{
//log out
}
return false;
}
