java - 仅显示一次对话框

Question

我有一个对话框窗口，其中包含容器和两个单击监听器来关闭对话框 我希望我只显示一次，我使用了这段代码，但它根本不显示!!

有什么帮助吗？

    SharedPreferences setting = getSharedPreferences("dialogprefs", 0);
    final SharedPreferences.Editor editor = setting.edit(); 
    {
           final Dialog dialog = new Dialog(this);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
            dialog.setContentView(R.layout.hint1);
            dialog.setCanceledOnTouchOutside(true);
            dialog.setTitle("Hint");
            View masterView = dialog.findViewById(R.id.LinearLayout1);
            masterView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    dialog.dismiss();
                    editor.putString("dialogshow", "0".toString());
                    editor.commit();
                }
            });
                View masterView1 = dialog.findViewById(R.id.imageView1);
                masterView1.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        dialog.dismiss();
                        editor.putString("dialogshow", "0".toString());
                        editor.commit();
                    }
            });
            if (setting.getString("dialogshow" , "0").equals("0")) {
                dialog.dismiss();
            }
            else {
            dialog.show();  
            }
    }

假设 setting.getString("dialogShow", "0") 的意思类似于 getString(name, defaultValue) 那么默认值为 "0" 如果尚未设置首选项，这意味着该对话框永远不会显示一次。也许您的意思是 setting.getString("dialogShow", "1")。
