有人可以帮我吗

Answer 1

I think the actual problem is that, you want to show a ProgressDialog or dismiss a ProgressDialog when your activity has been destroyed.
    So before showing or dismissing the dialog be sure that your activity is not destroy using this code !YourActivity.this.isDestroyed().
    Try this for that:

    private ProgressDialog progressDialog;
    try {
                    progressDialog = new ProgressDialog(mContext);
                    if (progressDialog != null && !progressDialog.isShowing() && !YourActivity.this.isDestroyed()) {
                        progressDialog.setMessage("Please wait..");
                        progressDialog.setCancelable(false);
                        progressDialog.show();
                    }
                }
                catch (Exception e) {
                    Log.e(TAG, "error", e);
                } 

    And when you dismiss dialog do this
    if(progressDialog.isShowing()){
    progressDialog.dismiss();
    }       

    Hope this will help you

如果您要创建Dialog getApplicationContext()作为其context参数，请将其更改为YourActivity.this。
