java– 非静态方法是googlePlayServicesAvailable,并且无法从静态上下文引用getErrorDialog

概述我正在编写此代码,它显示错误非静态方法GoogleApiAvailability.isGooglePlayServicesAvailable(上下文上下文)和GoogleApiAvailability.getErrorDialog(Activityactivity,interrorCode,intrequestCode)无法从静态上下文引用.packagecom.xamarin.gcmexample;importandroid.a

我正在编写此代码,它显示错误非静态方法GoogleAPIAvailability.isGooglePlayServicesAvailable(上下文上下文)和GoogleAPIAvailability.getErrorDialog(Activity activity,int errorCode,int requestCode)无法从静态上下文引用.

package com.xamarin.gcmexample;import androID.app.Dialog;import androID.os.Bundle;import androID.support.v7.app.AppCompatActivity;import com.Google.androID.gms.common.ConnectionResult;import com.Google.androID.gms.common.API.Googleapiclient;import com.Google.androID.gms.common.GoogleAPIAvailability;import androID.util.Log;import androID.Widget.TextVIEw;public class Main extends AppCompatActivity {    TextVIEw msgText;    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.main);        msgText = (TextVIEw) findVIEwByID(R.ID.msgText);    }    protected voID IsPlayServicesAvailable ()    {        int resultCode = GoogleAPIAvailability.isGooglePlayServicesAvailable(this);        if (resultCode == ConnectionResult.SUCCESS){            msgText.setText("isGooglePlayServicesAvailable SUCCESS");        }else{            GoogleAPIAvailability.getErrorDialog(this, resultCode, 1).show();        }    }}

解决方法:

努兰已经指出了正确的答案.

替换您的方法

protected voID IsPlayServicesAvailable() {    int resultCode = GoogleAPIAvailability.isGooglePlayServicesAvailable(this);    if (resultCode == ConnectionResult.SUCCESS){        msgText.setText("isGooglePlayServicesAvailable SUCCESS");    } else {        GoogleAPIAvailability.getErrorDialog(this, resultCode, 1).show();    }}

通过

protected voID IsPlayServicesAvailable() {    int resultCode = GoogleAPIAvailability.getInstance().isGooglePlayServicesAvailable(this);    if (resultCode == ConnectionResult.SUCCESS){        msgText.setText("isGooglePlayServicesAvailable SUCCESS");    } else {        GoogleAPIAvailability.getInstance().getErrorDialog(this, resultCode, 1).show();    }}
