谷歌地图应用程序关闭 - Android Studio

标签： java android google-maps android-fragments

我知道这个问题一次又一次被问到，但它还没有得到解答，我已经搜索了几个小时试图解决这个问题，但我正在开发的应用程序集成了谷歌地图。它利用滑出的侧导航抽屉，您可以选择然后切换视图的片段。话虽如此，我已经为此应用程序安装了所有必需的库，它可以正确编译和构建，但每当我点击包含应用程序的片段时，它就会崩溃。所以这是我的文件。

MainActivity.java - 

package com.raziel.android.publictoilet;

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;


public class MainActivity extends ActionBarActivity
    implements NavigationDrawerFragment.NavigationDrawerCallbacks {

/**
 * Fragment managing the behaviors, interactions and presentation of the navigation drawer.
 */
private NavigationDrawerFragment mNavigationDrawerFragment;

/**
 * Used to store the last screen title. For use in {@link #restoreActionBar()}.
 */
private CharSequence mTitle;

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

    mNavigationDrawerFragment = (NavigationDrawerFragment)
            getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
    mTitle = getTitle();

    // Set up the drawer.
    mNavigationDrawerFragment.setUp(
            R.id.navigation_drawer,
            (DrawerLayout) findViewById(R.id.drawer_layout));

}


@Override
public void onNavigationDrawerItemSelected(int position) {

     //Switches the Fragmentx.java

    Fragment fragment;
    switch (position){
        case 1:
            fragment = FirstFragment.newInstance(position + 1);
            break;

            break;
        case 3:
            fragment = ThirdFragment.newInstance(position + 1);
            break;

    }

    // update the main content by replacing fragments
    FragmentManager fragmentManager = getSupportFragmentManager();
    fragmentManager.beginTransaction()
            .replace(R.id.container, PlaceholderFragment.newInstance(position + 1))
            .commit();
}

public void onSectionAttached(int number) {
    switch (number) {
        case 1:
            mTitle = getString(R.string.title_section1);

            break;
        case 2:
            mTitle = getString(R.string.title_section2);
            break;
        case 3:
            mTitle = getString(R.string.title_section3);
            break;
        case 4:
            mTitle = getString(R.string.title_section4);
            break;
    }
}





public void restoreActionBar() {

    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);

        // Only show items in the action bar relevant to this screen
        // if the drawer is not showing. Otherwise, let the drawer
        // decide what to show in the action bar.
        getMenuInflater().inflate(R.menu.main, menu);
        restoreActionBar();
        return true;
    }
    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);

    private static final String ARG_SECTION_NUMBER = "section_number";

    /**

    public static PlaceholderFragment newInstance(int sectionNumber) {
        PlaceholderFragment fragment = new PlaceholderFragment();

    @Override

                //rootView = inflater.inflate(R.layout.fragment_info, container, false);
                break;
        }
        return rootView;
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        ((MainActivity) activity).onSectionAttached(
                getArguments().getInt(ARG_SECTION_NUMBER));
       }
   }

}

map.java - 这是一个真实的地图代码＆＃34;那是因为随着MainActivity下的侧面布局扩展了ActionBarActivity ... NavigationDrawerCallbacks它无法实现两个不同的回调函数。     包com.raziel.android.publictoilet; 

import android.app.Activity;
import android.os.Bundle;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class map extends Activity implements OnMapReadyCallback {

// Used to call the map and inflate fragment in container
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.map);

    MapFragment mapFragment = (MapFragment) getFragmentManager()
            .findFragmentById(R.id.the_map);
    mapFragment.getMapAsync(this);
}

@Override
public void onMapReady(GoogleMap map) {
    LatLng sydney = new LatLng(-33.867, 151.206);

    map.setMyLocationEnabled(true);
    map.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney, 13));

    map.addMarker(new MarkerOptions()
            .title("Sydney")
            .snippet("The most populous city in Australia.")
            .position(sydney));
     }
}

现在有一些部分。所有带有标签的东西都是名为map.xml -

的标签 
    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:paddingRight="@dimen/activity_horizontal_margin"
            android:paddingTop="@dimen/activity_vertical_margin"
            android:paddingBottom="@dimen/activity_vertical_margin"
            tools:context=".MainActivity$PlaceholderFragment">



<fragment xmlns:android="http://schemas.android.com/apk/res/android"
           android:name="com.google.android.gms.maps.SupportMapFragment"
           android:id="@+id/the_map"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           />

</RelativeLayout>

这是我的AndroidManifest.xml文件。这包含我的地图应用可能需要的所有必要部分，例如我的API_KEY。

logcat显示它是由：

引起的 
Caused by: java.lang.RuntimeException: API key not found.  Check that <meta-data android:name="com.google.android.geo.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

但问题是我无法更改AndroidManifest.xml文件来解决此问题，因为它会自动重新生成每个构建版本！而且你可以清楚地看到它在AndroidManifest.xml中。我已经尝试将其设为只读，但它只是编译永远不会丢失任何错误。谁能请帮忙。这也是在Android Studio中。

1 个答案:

答案 0 :(得分：0)

没关系我修好了。该应用程序正在生成AndroidManifest.xml文件，我正在尝试编辑它。那是错误的。正确的一个位于app / src / main中，我添加了我的密钥。感谢那个向我投票的家伙，真的很有帮助。
