问题描述

我已经得到了一个地图，以显示在屏幕上。我想创建地图上方的按钮，然后添加行动这一点。例如。该按钮将改变地图的位置。我基本上想我的code适应这个：。不过，我使用延伸片段活动，这打乱了一切。

I have managed to get a map to show on the screen. I am trying to create buttons above the map and then add actions to this. E.g. the button will change the location of the map. I am basically trying to adapt my code to this: https://www.youtube.com/watch?v=awX5T-EwLPc. However, I am using "extends Fragment Activity" which messes everything up.

我的问题：我无法创建地图上方的按钮时，它被放置在地图中。我试图创建地图上面的一个按钮，并指定code这样我就可以移动到地图等。这里的位置是我的code：

My problem: I cannot create a button above the map, it is placed inside the map. I am trying to create a button above the map, and assign code so I can move to a location on the map etc. Here is my code:

package com.example.theapp;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends FragmentActivity implements OnClickListener
{

    Button button;
    TextView text;

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

        button=(Button)findViewById(R.id.button1);
        text=(TextView)findViewById(R.id.textView1);
   }

    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub
        text.setText("The button worked!");

    }
}

activity_main.xml中

<?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:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment" />

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/map"
        android:layout_alignTop="@+id/map"
        android:text="Button" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/button1"
        android:layout_alignBottom="@+id/button1"
        android:layout_alignRight="@+id/map"
        android:layout_marginRight="39dp"
        android:text="TextView" />

</RelativeLayout>

从code，我的应用程序显示在地图和文本视图上的一个按钮。当您单击按钮，它的意思更改文本，但它不会做任何事情。我研究的教程和它的外观，我会创建多个片段？

From the code, my app displays a button on the map and a text view. When you click the button, its meant to change the text, but it doesn't do anything. I have researched tutorials and by the looks of it, I will have to create multiple fragments?

问：我如何将能够创建一个页面上的一个按钮，即会那么针点在地图上的用户

Question: How would I be able to create a button on that page, that will then pin point the user on the map?

感谢您提前。
