为什么会发生？我正在点击项目，但它没有响应

而我 调用另一个活动 ，并且还将一些值传递给该活动

看看我的日志说了什么：

代码使用点击任意列表项启动活动：

// selecting single ListView item
        ListView lv = getListView();

        // Launching new screen on Selecting Single ListItem
        lv.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                // getting values from selected ListItem
                String name = ((TextView) view.findViewById(R.id.name)).getText().toString();
                String emailID = ((TextView) view.findViewById(R.id.emailID)).getText().toString();
                String deviceID = ((TextView) view.findViewById(R.id.deviceID)).getText().toString();
                String password = ((TextView) view.findViewById(R.id.password)).getText().toString();

                // Starting new intent
                Intent in = new Intent(LicenseListActivity.this, LicenseCheckActivity.class);
                in.putExtra(TAG_NAME, name);
                in.putExtra(TAG_EMAIL_ID, emailID);
                in.putExtra(TAG_DEVICE_ID, deviceID);
                in.putExtra(TAG_PASSWORD, password);
                startActivity(in);
            }
        });
    }

Answer 1

哦，我的运气不好，我做了愚蠢的错误，我在列表项目中使用图像按钮，而不需要所以我做了更改，imagebutton到imageview并解决了问题！

 <ImageView
    android:id="@+id/imageButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_marginRight="10dp"
    android:background="@drawable/arrow" />

点击列表项无响应
