java - 第三次进入上一个活动时出现错误

Question

我正在尝试做一个按钮，而不是它的功能是转到 TabWidget 中的上一个活动

        btnVolver.setOnClickListener(new OnClickListener() 
        {
            @Override
            public void onClick(View arg0) 
            {
                String className = getIntent().getStringExtra("webpush");
                Class<?> webpushClass = null;
                try {
                    webpushClass = Class.forName(className);
                } catch (ClassNotFoundException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

                 Intent intent = new Intent(getApplicationContext(), webpushClass); 
                 intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
//               intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
//               intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
//               webPushActivity.this.finishActivity(RESULT_OK);
                 View vista = getLocalActivityManager().startActivity("prueba",
                         intent)
                            .getDecorView();
                       setContentView(vista);

A--> 实际活动。B--> 上一个活动

但是当我从 A 到 B，从 B 到 A，从 A 到 B（第三次点击）时，我得到下一个错误：

Answer 1

您StackOverflowError可能是由太多嵌套视图引起的（您的 logcat 内容也暗示了这一点）。

查看以下链接以获取更多参考：

Android StackOverflow 错误

java.lang.StackOverFlow 错误。怀疑浏览量过多？

Stackoverflow：由嵌套视图引起？

Answer 2

我不确定，但您是否尝试开始另一个活动并将视图设置为当前活动？
