安卓6.0及以上权限处理

自己封装的一个基Activity去处理安卓M权限的问题。

源码地址： https://github.com/anzhuojinjie/Permission

向系统请求权限

import android.content.DialogInterface; import android.content.Intent; import android.content.pm.PackageManager; import android.net.Uri; import android.os.Build; import android.provider.Settings; import android.support.annotation.NonNull; import android.support.v4.app.ActivityCompat; import android.support.v4.content.ContextCompat; import android.support.v7.app.AlertDialog; import android.support.v7.app.AppCompatActivity; import android.util.Log; import java.util.ArrayList; import java.util.List; /** * Created by Joe on 2016/11/29. */ public class MPermissionsActivity extends AppCompatActivity { private final String TAG = "MPermissions"; private int REQUEST_CODE_PERMISSIONS = 0x00099; /** * 向系统请求权限 * @param permissions 请求的权限 * @param requestCode 请求权限的请求码 */ public void requestPermission(String[] permissions,int requestCode){ this.REQUEST_CODE_PERMISSIONS = requestCode; if (checkPermission(permissions)){ successPermission(REQUEST_CODE_PERMISSIONS); }else { List<String> needPermissions = getDeniedPermissons(permissions); ActivityCompat.requestPermissions(this,needPermissions.toArray(new String[needPermissions.size()]),REQUEST_CODE_PERMISSIONS); } } /** * 检查是否已经被授予权限 * @param permissions * @return */ private boolean checkPermission(String[] permissions){ if (Build.VERSION.SDK_INT<Build.VERSION_CODES.M){ return true; } for (String permission : permissions){ if (ContextCompat.checkSelfPermission(this,permission) != PackageManager.PERMISSION_GRANTED){ return false; } } return true; } /** * 获取权限集中需要申请权限的列表 * @param permissions * @return */ private List<String> getDeniedPermissons(String[] permissions){ List<String> needRequestPermissionList = new ArrayList<>(); for (String permission : permissions){ if (ContextCompat.checkSelfPermission(this,permission) != PackageManager.PERMISSION_GRANTED || ActivityCompat.shouldShowRequestPermissionRationale(this,permission)){ needRequestPermissionList.add(permission); } } return needRequestPermissionList; } /** * 系统请求权限回调 * @param requestCode * @param permissions * @param grantResults */ @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); if (requestCode == REQUEST_CODE_PERMISSIONS){ if (verifyPermissions(grantResults)){ successPermission(REQUEST_CODE_PERMISSIONS); }else { failPermission(REQUEST_CODE_PERMISSIONS); showTipsDialog(); } } } private void showTipsDialog(){ new AlertDialog.Builder(this) .setTitle("提示信息") .setMessage("当前应用缺少必要权限，该功能暂时无法使用。如若需要，请单击【确定】按钮前往设置中心进行权限授权。") .setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { } }) .setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { startAppSetting(); } }) .show(); } /** * 确认所有权限是否被授权 * @param permissions * @return */ private boolean verifyPermissions(int[] permissions){ for (int permission : permissions){ if (permission != PackageManager.PERMISSION_GRANTED){ return false; } } return true; } /** * 启动当前应用设置界面 */ private void startAppSetting(){ Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS); intent.setData(Uri.parse("package:"+getPackageName())); startActivity(intent); } /** * 获取权限成功 * @param requestCode */ public void successPermission(int requestCode){ Log.i(TAG, "获取权限成功= "+requestCode); } /** * 获取权限失败 * @param requestCode */ public void failPermission(int requestCode){ Log.i(TAG, "获取权限失败= "+requestCode); } }

使用：在相应的Activity继承MPermissionsActivity

public class MainActivity extends MPermissionsActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } /** * 打电话 * * @param view */ public void onClick1(View view) { requestPermission(new String[]{Manifest.permission.CALL_PHONE}, 0x0001); } /** * 写SD卡 * * @param view */ public void onClick2(View view) { requestPermission(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 0x0002); } /** * 拍照 * * @param view */ public void onClick3(View view) { requestPermission(new String[]{Manifest.permission.CAMERA}, 0x0003); } /** * 权限成功回调函数 * * @param requestCode */ @Override public void successPermission(int requestCode) { super.successPermission(requestCode); switch (requestCode) { case 0x0001: Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:15253052133")); if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission. See the documentation // for ActivityCompat#requestPermissions for more details. return; } startActivity(intent); break; } } }
