Android的渲染谷歌地图一个片段内 [英] Android Render Google Map inside a Fragment

问题描述

如上图所示，我有一个片段活动而呈现两个fragements。在地图碎片，我想implment和显示地图。

由于我们需要扩大MapActivity我不知道它如何能在片段中完成。

想实现从解决方案 （<一href="http://stackoverflow.com/a/10739200/1737771">http://stackoverflow.com/a/10739200/1737771)

        窗口W = mLocalActivityManager.startActivity（标签，我）;
        查看currentView = w.getDecorView（）;
        currentView.setVisibility（View.VISIBLE）;
        currentView.setFocusableInTouchMode（真正的）;
        （（ViewGroup中）currentView）
                .setDescendantFocusability（ViewGroup.FOCUS_AFTER_DESCENDANTS）;

}
 

我应该怎么指定靠近

  ..............
公共查看onCreateView（LayoutInflater充气，容器的ViewGroup，
            捆绑savedInstanceState）{
        //这是你指定活动类
        意图I =新的意图（getActivity（），GMapActivity.class）;
        窗口W = mLocalActivityManager.startActivity（标签，我）;

解决方案

看看新谷歌地图Android的API这是刚刚发布的V2 。它包含片段（包括支持库）的支持以及更多。

As shown above i have a Fragment Activity which renders two fragements. On the Map Fragment i want to implment and display a Map.

Since we need to extend MapActivity i am not sure how it can be done inside a fragment.

Trying to implement Solution from (http://stackoverflow.com/a/10739200/1737771)

package com.m7.nomad;

import android.app.LocalActivityManager;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.actionbarsherlock.app.SherlockFragment;
import com.actionbarsherlock.view.Window;

public class MapsFragment extends SherlockFragment {
    private static final String KEY_STATE_BUNDLE = "localActivityManagerState";
    private LocalActivityManager mLocalActivityManager;

    protected LocalActivityManager getLocalActivityManager() {
        return mLocalActivityManager;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Bundle state = null;
        if (savedInstanceState != null) {
            state = savedInstanceState.getBundle(KEY_STATE_BUNDLE);
        }

        mLocalActivityManager = new LocalActivityManager(getActivity(), true);
        mLocalActivityManager.dispatchCreate(state);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // This is where you specify you activity class
        Intent i = new Intent(getActivity(), GMapActivity.class);
        Window w = mLocalActivityManager.startActivity("tag", i);
        View currentView = w.getDecorView();
        currentView.setVisibility(View.VISIBLE);
        currentView.setFocusableInTouchMode(true);
        ((ViewGroup) currentView)
                .setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);
        return currentView;

    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putBundle(KEY_STATE_BUNDLE,
                mLocalActivityManager.saveInstanceState());
    }

    @Override
    public void onResume() {
        super.onResume();
        mLocalActivityManager.dispatchResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        mLocalActivityManager.dispatchPause(getActivity().isFinishing());
    }

    @Override
    public void onStop() {
        super.onStop();
        mLocalActivityManager.dispatchStop();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mLocalActivityManager.dispatchDestroy(getActivity().isFinishing());
    }

}

What should i specify for near

..............
public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // This is where you specify you activity class
        Intent i = new Intent(getActivity(), GMapActivity.class);
        Window w = mLocalActivityManager.startActivity("tag", i);

..................

解决方案

Take a look at the new Google Maps Android API v2 that was just released. It contains support for fragments (including the support library) and much more.
