1.动态权限申请
模糊的位置信息android.permission.ACCESS_COARSE_LOCATION权限为例
在AndroidManifest文件中加入权限
然后java代码中动态申请
//动态申请权限的测试方法
public void test() {
// 要申请的权限 数组 可以同时申请多个权限
String[] permissions = {Manifest.permission.ACCESS_COARSE_LOCATION};
if (Build.VERSION.SDK_INT >= 23) {
//如果超过6.0才需要动态权限，否则不需要动态权限
//如果同时申请多个权限，可以for循环遍历
int check = ContextCompat.checkSelfPermission(this,permissions[0]);
// 权限是否已经 授权 GRANTED---授权 DINIED---拒绝
if (check == PackageManager.PERMISSION_GRANTED) {
//写入你需要权限才能使用的方法
run();
} else {
//手动去请求用户打开权限(可以在数组中添加多个权限) 1 为请求码 一般设置为final静态变量
requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
}
} else {
//写入你需要权限才能使用的方法
run();
}
}
其中run()为你自己需要权限才能执行的方法
然后重写申请权限的回掉方法
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
@NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
//回调，判断用户到底点击是还是否。
//如果同时申请多个权限，可以for循环遍历
if (requestCode == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//写入你需要权限才能使用的方法
run();
} else {
// 没有获取 到权限，从新请求，或者关闭app
Toast.makeText(this,"需要获得XXX权限",Toast.LENGTH_SHORT).show();
}
}
2.跳转GPS设置界面
相关字符串
提示 当前应用缺少必要权限。nn请点击"设置"-"权限"-打开所需权限。 当前应用需要打开定位功能。nn请点击"设置"-"定位服务"-打开定位功能。 设置 取消
java代码
private int GPS_REQUEST_CODE = 10;
private boolean checkGPSIsOpen() {
boolean isOpen;
LocationManager locationManager = (LocationManager) this
.getSystemService(Context.LOCATION_SERVICE);
isOpen = locationManager.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER);
return isOpen;
}
private void openGPSSettings() {
if (checkGPSIsOpen()) {
initLocation(); //自己写的定位方法
} else {
//没有打开则弹出对话框
new alertDialog.Builder(this)
.setTitle(R.string.notifyTitle)
.setMessage(R.string.gpsNotifyMsg)
// 拒绝, 退出应用
.setNegativeButton(R.string.cancel,
new DialogInterface.onClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
})
.setPositiveButton(R.string.setting,
new DialogInterface.onClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//跳转GPS设置界面
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(intent, GPS_REQUEST_CODE);
}
})
.setCancelable(false)
.show();
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GPS_REQUEST_CODE) {
//做需要做的事情，比如再次检测是否打开GPS了 或者定位
openGPSSettings();
}
}
最后在需要的地方调用 openGPSSettings()方法。
效果（是在相关权限是已经申请好的情况下的效果）
3.下面是我在高德地图Demo中看见的检测权限的Activity
public class CheckPermissionsActivity extends Activity implements
ActivityCompat.onRequestPermissionsResultCallback {
protected String[] needPermissions = {
Manifest.permission.ACCESS_COARSE_LOCATION,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.READ_PHONE_STATE
};
private static final int PERMISSON_REQUESTCODE = 0;
private static final int SETTING_REQUESTCODE = 1;
private boolean isNeedCheck = true;
@Override
protected void onResume() {
super.onResume();
if (isNeedCheck) {
checkPermissions(needPermissions);
}
}
private void checkPermissions(String... permissions) {
List needRequestPermissonList = findDeniedPermissions(permissions);
if (null != needRequestPermissonList
&& needRequestPermissonList.size() > 0) {
ActivityCompat.requestPermissions(this,
needRequestPermissonList.toArray(
new String[needRequestPermissonList.size()]),
PERMISSON_REQUESTCODE);
}
}
private List findDeniedPermissions(String[] permissions) {
List needRequestPermissonList = new ArrayList();
for (String perm : permissions) {
if (ContextCompat.checkSelfPermission(this,
perm) != PackageManager.PERMISSION_GRANTED
|| ActivityCompat.shouldShowRequestPermissionRationale(
this, perm)) {
needRequestPermissonList.add(perm);
}
}
return needRequestPermissonList;
}
private boolean verifyPermissions(int[] grantResults) {
for (int result : grantResults) {
if (result != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
return true;
}
@Override
public void onRequestPermissionsResult(int requestCode,
String[] permissions, int[] paramArrayOfInt) {
if (requestCode == PERMISSON_REQUESTCODE) {
if (!verifyPermissions(paramArrayOfInt)) {
showMissingPermissionDialog();
isNeedCheck = false;
}
}
}
private void showMissingPermissionDialog() {
alertDialog.Builder builder = new alertDialog.Builder(this);
builder.setTitle(R.string.notifyTitle);
builder.setMessage(R.string.notifyMsg);
// 拒绝, 退出应用
builder.setNegativeButton(R.string.cancel,
new DialogInterface.onClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
builder.setPositiveButton(R.string.setting,
new DialogInterface.onClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
startAppSettings();
}
});
builder.setCancelable(false);
builder.show();
}
private void startAppSettings() {
Intent intent = new Intent(
Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
intent.setData(Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, SETTING_REQUESTCODE);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
this.finish();
return true;
}
return super.onKeyDown(keyCode, event);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == SETTING_REQUESTCODE) {
checkPermissions(needPermissions);
}
}
}
继承于CheckPermissionsActivity即可
不允许就跳转系统设置界面，若没设置再次检测权限并申请，直到允许为止。可和GPS设置搭配使用
以上这篇Android 6.0动态权限及跳转GPS设置界面的方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持考高分网。
