从Android应用程序访问Google Maps Navigation

Question

I know this question has been asked multiple times, but I'm completely stuck. I am trying to use an Intent to pass an EditText value to Google Maps to use outside of my app. I have the basic syntax that I need, but not sure where I pass in the address. I'm wanting to use a regular address and not latitude/longitude.

The code I have to launch Google Maps is

public void sendMessage(View view)
{
    Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
            Uri.parse("http://maps.google.com/maps?daddr=address"));
    startActivity(intent);
}

And my XML for the value that I want passed in...

<EditText
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/addressEditText"
        android:layout_weight=".5"
        android:layout_marginRight="50dp"
        android:layout_marginBottom="-10dp"
        android:textColor="@android:color/primary_text_light"
        android:singleLine="true"
        android:padding="1dp"
        android:scaleType="centerCrop"
        android:cropToPadding="true"
        android:background="@drawable/border_image"/>

<Button
        android:id="@+id/routeButton"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="-60dp"
        android:layout_marginRight="40dp"
        android:layout_marginBottom="-10dp"
        android:layout_marginTop="-10dp"
        android:layout_weight=".4"
        android:text="Route"
        android:textColor="#FFF"
        android:textSize="16sp"
        android:onClick="sendMessage" />

I'm just wanting to take the text that is input in the address's EditText box and put into Google Maps Navigation as the destination using my current location upon clicking the "Route" button. Any help would be greatly appreciated!

You should extract the string from the EditText and attach it to the Uri like this:

String map = "http://maps.google.co.in/maps?q=" + yourAddress;
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(map));
startActivity(intent);
