一、 1个运行时权限处理

Android 6.0 及以上时只需要1个运行权限处理，如CALL_PHONE权限：

在AndroidManifest.xml中声明权限：

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

申请运行权限：

public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        Button call = (Button) findViewById(R.id.call);        call.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                if (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {                    ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CALL_PHONE}, 1);                } else {                    call();                }            }        });    }    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        super.onRequestPermissionsResult(requestCode, permissions, grantResults);        switch (requestCode) {            case 1:                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {                    call();                } else {                    Toast.makeText(this, "You denied the permission", Toast.LENGTH_SHORT).show();                }                break;            default:                break;        }    }    private void call() {        try {            Intent intent = new Intent(Intent.ACTION_CALL);            intent.setData(Uri.parse("tel:10086"));            startActivity(intent);        } catch (SecurityException e) {            e.printStackTrace();        }    }}

二、多个运行时权限处理

Android 6.0 及以上时只需要多个运行权限处理，如：READ_PHONE_STATE、ACCESS_FINE_LOCATION、WRITE_EXTERNAL_STORAGE等

protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        List<String> permissionList = new ArrayList<>();        if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.ACCESS_FINE_LOCATION)!= PackageManager.PERMISSION_GRANTED) {            permissionList.add(Manifest.permission.ACCESS_FINE_LOCATION);        }        if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_PHONE_STATE)!= PackageManager.PERMISSION_GRANTED) {            permissionList.add(Manifest.permission.READ_PHONE_STATE);        }        if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED) {            permissionList.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);        }        if (!permissionList.isEmpty()) {            String[] permissions = permissionList.toArray(new  String[permissionList.size()]);            ActivityCompat.requestPermissions(MainActivity.this, permissions, 1);        } else {            doyourfunction();        }    }    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        super.onRequestPermissionsResult(requestCode, permissions, grantResults);        switch (requestCode) {            case 1:                if (grantResults.length > 0 ) {                    for (int result : grantResults) {                        if (result != PackageManager.PERMISSION_GRANTED) {                            Toast.makeText(this, "必须同意所有权限才能使用本程序",Toast.LENGTH_LONG).show();                            finish();                            return;                        }                    }                    doyourfunction();                } else {                    Toast.makeText(this, "发生未知错误",Toast.LENGTH_LONG).show();                    finish();                }                break;            default:                break;        }    }
