我必须在启动应用程序时请求权限，但是，应用程序的其余部分在对话框的答案之前开始工作，这会导致活动未获得使用权限的问题，直到即使授予了权限，它也会重新启动。
如何在继续使用应用程序的其余部分之前等待响应？
答案 0 :(得分：0)
我在其中一个应用中面临同样的问题，我需要在虚拟助手聊天屏幕上准备好所有权限。我在虚拟活动中收集位置，音频和存储权限，并带有一些反映其状态的复选框。当我的应用程序具有所有三个基本权限时，我将其从虚拟活动跳转到主要聊天活动。 我在这里粘贴了整个Dummy Activity代码，可能需要进行一些清理，所以只需要你需要的东西：
public class bootActivity extends Activity {
Context ctx;
private CheckBox checkboxLocation;
private CheckBox checkboxAudioRecording;
private CheckBox checkboxStorage;
private Activity thisActivity;
private String[] permissionsArray=new String[]{Manifest.permission.RECORD_AUDIO,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.WRITE_EXTERNAL_STORAGE,};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
app.loge("BOOTING....START");
setContentView(R.layout.activity_boot);

app.setBootingTRUE(getApplicationContext());
ctx=getApplicationContext();

checkboxLocation.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if(b==true) {

app.loge("Requesting LOCATION permission");
ActivityCompat.requestPermissions(thisActivity, permissionsArray,appPermissionsCallbackConstant);
}
}
refreshUI();
if((!needPermissionLocation())&&(!needPermissionRecordAudio())&&(!(needPermissionStorage()))){
launchApp();
