Android6.0的动态权限的简单使用

权限工具activity：

public class BaseActivity extends AppCompatActivity {
public String[] permissions = new String[]{ //申请的权限
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.BODY_SENSORS,
Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.ACCESS_FINE_LOCATION};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}

/**
* 判断系统版本是否是Android6.0以上
* @return
*/
protected boolean isSystemVersionLarge23(){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
return true;
}else {
return false;
}
}

/**
* 检查多个权限是否被授予
* @param permissions 被检查权限名
* @return
*/
protected boolean checkMorePermission(String[] permissions){
boolean isAllCheck = false;
for (int i = 0; i < permissions.length; i++) {
if (ContextCompat.checkSelfPermission(this,permissions[i]) != PackageManager.PERMISSION_GRANTED){
isAllCheck = true;
break;
}
}
if (isAllCheck){
return false;
}else {
return true;
}
}

/**
* 检查单个权限是否被授予
* @param permission 被检查权限名
* @return
*/
protected boolean checkOnePermission(String permission){
if (ContextCompat.checkSelfPermission(this,permission) != PackageManager.PERMISSION_GRANTED){
return false;
}else{
return true;
}
}

/**
* 请求权限一个或多个
* @param permissions
* @param requestCode
*/
protected void requestOneOrMorePermissions(String[] permissions,int requestCode,AppCompatActivity activity){
boolean isAllCheck = false;
for (int i = 0; i < permissions.length; i++) {
if (!checkOnePermission(permissions[i])){
isAllCheck = true;
break;
}
}
if (isAllCheck){
ActivityCompat.requestPermissions(activity,permissions,requestCode);
}
}

/**
* 获取应用版本号
* @return
* @throws PackageManager.NameNotFoundException
*/
protected float getVersionCode(){
float versionCode = 0;
try {
versionCode = getPackageManager().getPackageInfo(getPackageName(),0).versionCode;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
return versionCode;
}

public void requestSDcardPermission(AppCompatActivity activity,int resultcode){
//检查SDcard权限
if (activity.checkCallingOrSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED
&& activity.checkCallingOrSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE},resultcode);
}

}
public void requestSensorPermission(AppCompatActivity activity,int resultcode){
//检查传感器权限
if (activity.checkCallingOrSelfPermission(Manifest.permission.BODY_SENSORS) != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.BODY_SENSORS},resultcode);
}
}

public void requestPositionPermission(AppCompatActivity activity,int resultcode){
//检查位置权限
if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION},resultcode);
}
}
}


继承Baseactivity一次请求多个权限：
public class LauchActivity extends BaseActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.lauch_activity);

//判断系统版本是否是6.0
if (isSystemVersionLarge23()){
checkPermission();
}else {
prepare();
}

}

private void prepare(){
//操作
}

private void checkPermission(){

if (checkMorePermission(permissions)){
prepare();
}else {
requestOneOrMorePermissions(permissions,11,this);//一次请求多个权限
}
}

//申请权限回调 Android6.0以上才会调用
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode){
case 11:
if (grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
//所有权限通过才会
prepare();
}else {
//拒绝一个就会这出现
showHintDialog("获取权限失败！");
}
break;
}
}

/**
* 拒绝权限弹出提示
* @param messege
*/
protected void showHintDialog(String messege){
AlertDialog dialog = new AlertDialog.Builder(this).create();
dialog.setMessage(messege);
dialog.setButton(DialogInterface.BUTTON_POSITIVE, "授权", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
checkPermission();
dialog.dismiss();
}
});
dialog.setButton(DialogInterface.BUTTON_NEGATIVE, "退出", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
dialog.dismiss();
}
});
dialog.show();
}
}


继承Baseactivity一次请求一个权限：

requestSDcardPermission(this,111);
requestSensorPermission(this,112);
requestPositionPermission(this,113);
/**
* Android6.0以上动态权限回调
* @param requestCode
* @param permissions
* @param grantResults
*/
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode){
case 111:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
//权限通过
}else {
//拒绝一个就会这出现

}
break;
case 112:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
//权限通过

}else {
//拒绝一个就会这出现

}
break;
case 113:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
//所有权限通过才会
}else {
//拒绝一个就会这出现

}
break;
default:
super.onRequestPermissionsResult(requestCode,permissions,grantResults);
break;
}

}
