我已经创建了这个课程，我需要在哪里放置我的最后一个位置？

public class DescriptionActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks {

    TextView t;
    Button up;
    GoogleApiClient mGoogleApiClient;
    LocationManager locationManager;
    LocationListener locationListener;

我试图激活GPS，它总是希望我检查权限怎么解决？在互联网上看了很多例子我已经成功获得激活GPS设备的对话但是当我试图获得位置时我有问题

Answer 1

如果要与提供的某个Google API建立连接在Google Play服务库中（例如Google登录，游戏或驱动器），您需要创建一个GoogleApiClient实例（“Google API 客户端“）.Google API客户端为所有人提供了一个公共入口点 Google Play服务和管理之间的网络连接用户的设备和每个Google服务。

自动管理与Google Play服务的连接。
对任何Google执行同步和异步API调用播放服务。
手动管理与Google Play服务的连接极少数情况下这是必要的。

将此添加到清单文件

imgview = (ImageView) findViewById(R.id.imgtrans);
Drawable d = getResources().getDrawable(R.drawable.image1);
int h = d.getIntrinsicHeight();
int w = d.getIntrinsicWidth();



if(d.getIntrinsicHeight()==797 && d.getIntrinsicWidth()==1218)
{
    imgtrans.getLayoutParams().width = ViewGroup.LayoutParams.MATCH_PARENT;
    imgtrans.getLayoutParams().height = someValue;
    imgtrans.requestLayout();
}

在您的活动中添加此代码

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.google.android.gms.location.sample.basiclocationsample" >

  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
</manifest>
