下面是我的应用程序代码。我尝试过这方面的工作，但没有遇到任何对我成功的事情。不变成 fragment 我能做什么。
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.my_account) {
} else if (id == R.id.nav_news) {
} else if (id == R.id.nav_live) {
} else if (id == R.id.nav_media) {
} else if (id == R.id.nav_calendar) {
} else if (id == R.id.nav_results) {
} else if (id == R.id.nav_about) {
} else if (id == R.id.nav_shop) {
} else if (id == R.id.nav_social_media) {
} else if (id == nav_fanzone) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
最佳答案
将您的 onNavigationItemSelected() 更改为:
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
switch(item.getItemId()){
case R.id.my_account:
//Do code here
break;
case R.id.nav_news:
//Do code here
break;
case R.id.nav_live:
//Do code here
break;
case R.id.nav_media:
//Do code here
break;
case R.id.nav_calendar:
//Do code here
break;
case R.id.nav_results:
//Do code here
break;
case R.id.nav_about:
//Do code here
break;
case R.id.nav_shop:
//Do code here
break;
case R.id.nav_social_media:
//Do code here
break;
case R.id.nav_fanzone:
//Do code here
break;
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
对于更改 Activity ，只需在所有switch cases中添加:
Intent intent=new Intent(your_activity.this,your_next_activity.class);
startActivity(intent);
关于java - 我正在尝试使用抽屉导航而不是 fragment 在 Activity 之间切换，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45289035/
