我有一個Android Studio的抽屜菜單。如何在點擊抽屜菜單項時更改活動?
我的菜單代碼:
//Menü kodları//
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.setItemIconTintList(null);
}
@Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
@Override
public boolean onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.menu_fbdown) {
} else if (id == R.id.menu_instadown) {
} else if (id == R.id.menu_twitdown) {
} else if (id == R.id.menu_privacy) {
} else if (id == R.id.menu_about) {
} else if (id == R.id.menu_contact) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
我要讓clicktable此菜單。我厭倦了這樣的代碼:
Intent i = new Intent(FBDownActivity.this, FBDownActivity.class);
startActivity(i);
像這樣:
@Override
public boolean onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.menu_fbdown) {
Intent i = new Intent(FBDownActivity.this, FBDownActivity.class);
startActivity(i);
} else if (id == R.id.menu_instadown) {
Intent i = new Intent(FBDownActivity.this, FBDownActivity.class);
startActivity(i);
} else if (id == R.id.menu_twitdown) {
} else if (id == R.id.menu_privacy) {
} else if (id == R.id.menu_about) {
} else if (id == R.id.menu_contact) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
但它沒有工作。仍然無法點擊項目。 我能做些什麼?
謝謝。
它確實有效。它開始了相同的活動 –
代碼看起來正確。它應該工作。嘗試開始不同的活動以明顯注意到變化。 –
如果你有時間,我給你團隊查看器ID並連接我,並期待項目?如果你有時間。 –
