这里介绍两种方式，如下：

一、逐次

private static final int PERMISSION_READ_EXTERNAL_STORAGE = 101;
private static final int PERMISSION_WRITE_EXTERNAL_STORAGE = 102;
private static final int PERMISSION_CAMERA = 103;
private void requestPermission() {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)== PackageManager.PERMISSION_DENIED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, PERMISSION_WRITE_EXTERNAL_STORAGE);
}
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, PERMISSION_READ_EXTERNAL_STORAGE);
}
if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) == PackageManager.PERMISSION_DENIED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA}, PERMISSION_CAMERA);
}
}

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int []grantResults) {
switch (requestCode) {
case PERMISSION_CAMERA: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

} else {
Toast.makeText(this, "没有摄像头权限我什么都做不了哦!", Toast.LENGTH_LONG).show();
}
break;
}
case PERMISSION_READ_EXTERNAL_STORAGE: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

} else {
Toast.makeText(this, "请打开存储读写权限，确保APP正常运行", Toast.LENGTH_LONG).show();;
}
break;
}
case PERMISSION_WRITE_EXTERNAL_STORAGE: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

} else {
Toast.makeText(this, "请打开存储读写权限，确保APP正常运行", Toast.LENGTH_LONG).show();;
}
break;
}
}
}

二、全部

private void requestPermission() {    List<String> permissionsNeeded = new ArrayList<String>();    if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)== PackageManager.PERMISSION_DENIED) {        permissionsNeeded.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);    }    if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED) {        permissionsNeeded.add(Manifest.permission.READ_EXTERNAL_STORAGE);    }    if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) == PackageManager.PERMISSION_DENIED) {        permissionsNeeded.add(Manifest.permission.CAMERA);    }    if(permissionsNeeded.size()>0){        ActivityCompat.requestPermissions(this, permissionsNeeded.toArray(new String[permissionsNeeded.size()]), 1);    }}@Overridepublic void onRequestPermissionsResult(int requestCode, String permissions[], int []grantResults) {    switch (requestCode) {        case 1: {            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {                if (grantResults.length > 0 && grantResults[1] == PackageManager.PERMISSION_GRANTED) {                    if (grantResults.length > 0 && grantResults[2] == PackageManager.PERMISSION_GRANTED) {                    } else {                        dialog();                    }                } else {                    dialog();                }            } else {                dialog();            }            break;        }    }}
