Android 6.0动态权限申请--事例代码

来源：互联网发布：贴吧防秒删软件编辑：程序博客网时间：2024/05/02 01:46

Android 6.0之后，为了保护用户隐私，将一些权限的申请放在了应用运行的时候去申请。并且，Android 6.0之后，将权限分为普通权限和特殊权限。

可以这样理解，Android 6.0之前，所有的权限都是普通权限，只要用户在安装时确认权限即可。Android 6.0之后，有部分权限变为特殊权限，需要应用运行时动态申请。

这里给出项目中写的模版代码。模版代码的目的为：动态申请多个权限，若有申请未被允许，则退出应用。

AndroidManifest.xml权限申请部分：

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />    <uses-permission android:name="android.permission.BLUETOOTH" />    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

MainActivity.java代码部分：

import android.Manifest;import android.content.pm.PackageManager;import android.os.Build;import android.support.annotation.NonNull;import android.support.v4.app.ActivityCompat;import android.support.v4.content.ContextCompat;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.widget.Toast;import java.util.ArrayList;import java.util.List;public class MainActivity extends AppCompatActivity {    private static final int REQUEST_CODE = 1;    private String[] getManifextPermissions() {        // all permissions in AndroidManifext.xml        // for android don't let me get them dynamically, it is ugly to code like this        return new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE                , Manifest.permission.BLUETOOTH                , Manifest.permission.BLUETOOTH_ADMIN                , Manifest.permission.ACCESS_COARSE_LOCATION};    }    private void requestAuthorities() {        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {            // permissions0 means permissions require requesting            final List<String> permissions0 = new ArrayList<>();            for (String permission : getManifextPermissions()) {                if (ContextCompat.checkSelfPermission(this, permission)                        != PackageManager.PERMISSION_GRANTED) {                    permissions0.add(permission);                }            }            if (!permissions0.isEmpty()) {                String[] permissions1 = new String[permissions0.size()];                for (int i = 0; i < permissions0.size(); i++) {                    permissions1[i] = permissions0.get(i);                }                // request permission one by one                ActivityCompat.requestPermissions(this,                        permissions1,                        REQUEST_CODE                );            } else {                permissionsPermited();            }        } else {            permissionsPermited();        }    }    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        if (requestCode == REQUEST_CODE) {            boolean isForbidden = false;            for (int i = 0; i < grantResults.length; i++) {                if (grantResults[i] != 0) {                    isForbidden = true;                    break;                }            }            if (isForbidden) {                permissionsDenied();            } else {                permissionsPermited();            }        }    }    private void permissionsPermited() {        new Thread() {            @Override            public void run() {                System.out.println("afx all permissions are permitted");            }        }.start();    }    private void permissionsDenied() {        Toast.makeText(this, "At least one permission is denied", Toast.LENGTH_LONG).show();        finish();    }    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        requestAuthorities();    }}
