Android开发拨打电话功能

直接看代码吧：

if (!EasyPermissions.hasPermissions(mFragment!!.context!!, *CALL_PHONE)) {
        EasyPermissions.requestPermissions(mFragment, mFragment.getString(R.string.call_permission), REQUEST_CODE_CALL_PHONE, *CALL_PHONE)
    } else {

        UtilHelper.call2(mFragment!!.context!!, tel)
        //360手机判断权限方法对它都没有，只好如果2s后，如果拨打电话界面不出来，还是本界面，证明没权限拨打不了
        if (Build.MANUFACTURER == "360"){
            Observable.timer(2,TimeUnit.SECONDS)
                    .observeOn(AndroidSchedulers.mainThread())
                    .subscribe(Consumer {
                        if (ActivityUtils.isForeground(mActivity)){
                            appSettingDialog(mActivity, "拨打电话权限")
                        }
                    })
        }
    }

其中

fun call2(activity: Context?, phone: String?) {
    if (activity == null || phone.isNullOrBlank()) {
        return
    }
    val intent = Intent(Intent.ACTION_CALL, Uri.parse("tel:$phone"))
    if (ContextCompat.checkSelfPermission(activity!!, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        //不具有打电话权限，需要进行权限申请
        ToastUtils.showCustomToast("没有电话权限")
        return
    }

    try {
        activity.startActivity(intent)
    }catch (e:java.lang.Exception){
        e.printStackTrace()
    }

}

fun appSettingDialog(context: Activity, str: String) {
    Toast.makeText(context, "已拒绝权限" + str + "并不再询问", Toast.LENGTH_SHORT).show()
    AppSettingsDialog.Builder(context)
            .setTitle("永久禁止权限访问")
            .setRationale("此功能需要$str，否则无法正常使用，是否打开设置")
            .setPositiveButton("好")
            .setNegativeButton("不行")
            .build()
            .show()
}
