為什么你這個(gè)代碼我加進(jìn)去之后，感覺(jué)好像三個(gè)覆蓋在一起了呢？

設(shè)置三個(gè)Button，都設(shè)置相同的?onClick?方法
<Button
????android:id="@+id/map_common"
????android:layout_width="wrap_content"
????android:layout_height="wrap_content"
????android:onClick="clickMe"
????android:text="普通地圖"/>

<Button
????android:id="@+id/map_site"
????android:layout_width="wrap_content"
????android:layout_height="wrap_content"
????android:onClick="clickMe"
????android:text="衛(wèi)星地圖"/>

<Button
????android:id="@+id/map_traffic"
????android:layout_width="wrap_content"
????android:layout_height="wrap_content"
????android:onClick="clickMe"
????android:text="實(shí)時(shí)交通OFF"/>
????
????
????
????在Activity中
????public?void?clickMe(View?v){
????switch?(v.getId()){
????????case?R.id.map_common:
????????????//普通地圖
????????????mBaidumap.setMapType(BaiduMap.MAP_TYPE_NORMAL);
????????????break;

????????case?R.id.map_site:
????????????//衛(wèi)星地圖
????????????mBaidumap.setMapType(BaiduMap.MAP_TYPE_SATELLITE);
????????????break;

????????case?R.id.map_traffic:
????????????//實(shí)時(shí)交通：如果打開(kāi)了，再次點(diǎn)擊就關(guān)閉；關(guān)閉了，再次點(diǎn)擊就打開(kāi)
????????????if(mBaidumap.isTrafficEnabled()){
????????????????mBaidumap.setTrafficEnabled(false);
????????????????Button?bt?=?(Button)?v;
????????????????bt.setText("實(shí)時(shí)交通OFF");
????????????}else{
????????????????mBaidumap.setTrafficEnabled(true);
????????????????Button?bt?=?(Button)?v;
????????????????bt.setText("實(shí)時(shí)交通ON");
????????????}
????????????break;

????????default:
????????????break;
????}
}

現(xiàn)在手機(jī)都沒(méi)有菜單項(xiàng)

同問(wèn) 魅族手機(jī)沒(méi)有菜單鍵
