android检测SD卡读写权限详情，我浪费了自己职业生涯的黄金5年
作者：互联网
requestPermission(HDCivilizationConstants.SD_CARD_REQUEST_CODE, “android.permission.WRITE_EXTERNAL_STORAGE”, new Runnable() {
@Override
public void run() {
//第一个Runnable
if (type==1){
FileUtils.saveBitmapPng(rectBitmap, pathList, 80);
}else{
try {
FileUtils.saveBitmapJPG(rectBitmap, pathList, 70);
} catch (ContentException e) {
e.printStackTrace();
}
}
}
}, new Runnable() {
@Override
public void run() {
//第二个Runnable
// UiUtils.getInstance().showToast(“请查看SD卡的读写权限”);
OKPopup.getInstance().showPopup(TakeCameraActivity.this, new OKPopup.BtnClickListener() {
@Override
public void btnOk() {
OKPopup.getInstance().dismissDialog();
}
}, false,

HDCivilizationConstants.SDCARD_PERMISSION);
}
});
2.调用上面的那个方法之后会跳转至这个方法（代码如下）：
/**
-
请求权限
-
@param id 请求授权的id 唯一标识即可
-
@param permission 请求的权限
-
@param allowableRunnable 同意授权后的操作
-
@param disallowableRunnable 禁止权限后的操作
*/
protected void requestPermission(int id, String permission, Runnable allowableRunnable, Runnable disallowableRunnable) {
if(allowableRunnable!=null){
allowablePermissionRunnables.put(id, allowableRunnable);
}
if (disallowableRunnable != null) {
disallowablePermissionRunnables.put(id, disallowableRunnable);
}
//api版本判断
if (Build.VERSION.SDK_INT >= 23) {
UiUtils.getInstance().showToast(“1”);
//减少是否拥有权限checkCallPhonePermission != PackageManager.PERMISSION_GRANTED
int checkCallPhonePermission = ContextCompat.checkSelfPermission(getApplicationContext(), permission);
if (checkCallPhonePermission != PackageManager.PERMISSION_GRANTED) {
UiUtils.getInstance().showToast(“2”);
//弹出对话框接收权限
ActivityCompat.requestPermissions(TakeCameraActivity.this, new String[]{permission}, id);
return;
} else {
UiUtils.getInstance().showToast(“3”);
if(allowableRunnable!=null){
allowableRunnable.run();
}
}
} else {
boolean result = PermissionChecker.checkSelfPermission(this, permission)
== PermissionChecker.PERMISSION_GRANTED;
if(!result){
UiUtils.getInstance().showToast(“4”);
//如果未授权
ActivityCompat.requestPermissions(TakeCameraActivity.this, new String[]{permission}, id);
}else{
UiUtils.getInstance().showToast(“5”);
if(allowableRunnable!=null){
allowableRunnable.run();
}
}
}
}
3.onRequestPermissionsResult方法是响应2中的方法之后执行。执行代码之后，开始执行Runnable中的代码程序。
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Runnable allowRun = allowablePermissionRunnables.get(requestCode);
if(allowRun!=null){
allowRun.run();
}
} else {
Runnable disallowRun = disallowablePermissionRunnables.get(requestCode);
if(disallowRun!=null){
disallowRun.run();
