我正在开发Android应用程序并使用GoogleMaps API v2.此应用程序到目前为止工作,但我想在地图中搜索路径:

我的代码:

Position_mark = new LatLng(35.7008, 51.437);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(Position_mark, 15));
map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
map.setOnMapClickListener(this);
map.setOnMapLongClickListener(this);
map.setOnMarkerDragListener(this);

...

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    //Used to put dark icons on light action bar

    mGoItem = menu.add(0, Delete_ITEM_ID, 0, null);
    mGoItem.setIcon(R.drawable.ic_launcher)
           .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

    SearchView searchView = 
        new SearchView(getSupportActionBar().getThemedContext());
    searchView.setQueryHint("Search for Places…");
    searchView.setIconified(false);

    menu.add("Search")
        .setIcon(R.drawable.abs__ic_search)
        .setActionView(searchView)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

        @Override
        public boolean onQueryTextSubmit(String newText) {
            return true;
        }

        /**
         * Called when the query text is changed by the user.
         * …

我编写了一个使用ussd代码的应用程序.我想发送一个ussd的请求,但我不知道如何获取数据并将其保存在String中.

示例代码:

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

    Button btn = (Button) findViewById(R.id.button1);

    btn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            String encodedHash = Uri.encode("#");
            String ussd = "*141*1" + encodedHash;
            startActivityForResult(new Intent("android.intent.action.CALL",
                    Uri.parse("tel:" + ussd)), 1);

        }
    });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);

    Toast.makeText(getApplicationContext(),
            "USSD: " + requestCode + "  " + resultCode + " ", 1).show(); …

我希望通过Wifi获取位置并在谷歌地图中工作,这对我不起作用,但Gps没问题,也没问题.

我的代码:

locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

if (locationManager != null) {
    boolean gpsIsEnabled = locationManager
            .isProviderEnabled(LocationManager.GPS_PROVIDER);
    boolean networkIsEnabled = locationManager
            .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

    if (gpsIsEnabled) {
        locationManager.requestLocationUpdates(
                LocationManager.GPS_PROVIDER, 5000L, 10F,
                (android.location.LocationListener) this);
    } else if (networkIsEnabled) {
        locationManager.requestLocationUpdates(
                LocationManager.NETWORK_PROVIDER, 5000L, 10F,
                (android.location.LocationListener) this);
    } else {
        // Show an error dialog that GPS is disabled...
    }
} else {
    // Show some generic error dialog because something must have gone
    // wrong with location manager.
}

AndroidManifest:

<uses-library android:name="com.google.android.maps" />

<meta-data
    android:name="com.google.android.maps.v2.API_KEY" …

我编写了使用AlarmManager的应用程序,它的工作非常好但是当用户使用电话说话时,音乐在alarmManager中播放,因此对用户来说不好.

如何在电话忙时禁用AlarmManager

谢谢...

我有我的活动布局,这个布局包含很多小部件.在我从Listview中的webservice加载的活动数据中.当listview被改编并填写所有数据时.imagview是看不见的但我想在数据加载时将Listview显示在Listview下面.

我在activity_main.xml中的代码:
