android 自定义封装android 6.0以上动态权限添加工具类
android开发过程中,动态权限添加时避免不了的,我看过别的添加权限的好多文章,但大多数添加的过程太过臃肿,代码量大。很不合理,于是乎,自己封装了一个工具类。很简单,来上代码。
package com.example.zsh.sendmessagedemo;
import android.app.Activity;
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 java.util.ArrayList;
import java.util.List;
public class PermissionTool {
private final int mRequestCode = 100;//权限请求码
public static boolean showSystemSetting = true;
private PermissionTool() {
}
private static PermissionTool permissionsUtils;
private IPermissionsResult mPermissionsResult;
public static PermissionTool getInstance() {
if (permissionsUtils == null) {
permissionsUtils = new PermissionTool();
}
return permissionsUtils;
}
public void chekPermissions(Activity context, String[] permissions, @NonNull IPermissionsResult permissionsResult) {
mPermissionsResult = permissionsResult;
if (Build.VERSION.SDK_INT < 23) {//6.0才用动态权限
permissionsResult.passPermissons();
return;
}
//创建一个mPermissionList,逐个判断哪些权限未授予,未授予的权限存储到mPerrrmissionList中
List<String> mPermissionList = new ArrayList<>();
//逐个判断你要的权限是否已经通过
for (int i = 0; i < permissions.length; i++) {
if (ContextCompat.checkSelfPermission(context, permissions[i]) != PackageManager.PERMISSION_GRANTED) {
mPermissionList.add(permissions[i]);//添加还未授予的权限
}
}
//申请权限
if (mPermissionList.size() > 0) {//有权限没有通过,需要申请
ActivityCompat.requestPermissions(context, permissions, mRequestCode);
} else {
//说明权限都已经通过,可以做你想做的事情去
permissionsResult.passPermissons();
return;
}
}
//请求权限后回调的方法
//参数: requestCode 是我们自己定义的权限请求码
//参数: permissions 是我们请求的权限名称数组
//参数: grantResults 是我们在弹出页面后是否允许权限的标识数组,数组的长度对应的是权限名称数组的长度,数组的数据0表示允许权限,-1表示我们点击了禁止权限
public void onRequestPermissionsResult(Activity context, int requestCode, @NonNull String[] permissions,
@NonNull int[] grantResults) {
boolean hasPermissionDismiss = false;//有权限没有通过
if (mRequestCode == requestCode) {
for (int i = 0; i < grantResults.length; i++) {
if (grantResults[i] == -1) {
hasPermissionDismiss = true;
}
}
//如果有权限没有被允许
if (hasPermissionDismiss) {
if (showSystemSetting) {
showSystemPermissionsSettingDialog(context);//跳转到系统设置权限页面,或者直接关闭页面,不让他继续访问
} else {
mPermissionsResult.forbitPermissons();
}
} else {
//全部权限通过,可以进行下一步操作。。。
mPermissionsResult.passPermissons();
}
}
}
/**
* 不再提示权限时的展示对话框
*/
AlertDialog mPermissionDialog;
private void showSystemPermissionsSettingDialog(final Activity context) {
final String mPackName = context.getPackageName();
if (mPermissionDialog == null) {
mPermissionDialog = new AlertDialog.Builder(context)
.setMessage("已禁用权限,请手动授予")
.setPositiveButton("设置", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
cancelPermissionDialog();
Uri packageURI = Uri.parse("package:" + mPackName);
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS, packageURI);
context.startActivity(intent);
context.finish();
}
})
.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//关闭页面或者做其他操作
cancelPermissionDialog();
//mContext.finish();
mPermissionsResult.forbitPermissons();
}
})
.create();
}
mPermissionDialog.show();
}
//关闭对话框
private void cancelPermissionDialog() {
if (mPermissionDialog != null) {
mPermissionDialog.cancel();
mPermissionDialog = null;
}
}
public interface IPermissionsResult {
void passPermissons();
void forbitPermissons();
}
}
用的时候直接调用,如下:
// 把需要的权限添加到String[]数组中即可
PermissionTool.getInstance().chekPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CAMERA,
Manifest.permission.WRITE_CALENDAR, Manifest.permission.CALL_PHONE,
Manifest.permission.SEND_SMS,
Manifest.permission.RECORD_AUDIO}, new PermissionTool.IPermissionsResult() {
@Override
public void passPermissons() {
// 通过权限的操作
}
@Override
public void forbitPermissons() {
// 拒绝权限的操作
}
});
}
