我发现导致它的视图，但我不明白为什么以及如何在将来避免它。

这是我在布局文件中的视图，并在代码中初始化它：

<LinearLayout
                android:id="@+id/terms_button_layout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginBottom="@dimen/dp10"
                android:background="@drawable/car_component_border"
                android:padding="@dimen/cell_padding_top" >

                <ImageView
                    android:id="@+id/terms_image"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:src="@drawable/terms" />

                <TextView
                    android:id="@+id/terms_text"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="@string/terms_of_use"
                    android:textAppearance="?android:attr/textAppearanceLarge" />
            </LinearLayout>


terms = (LinearLayout) findViewById(R.id.terms_button_layout);

我做错了什么？

重新启动应用程序时的运行时和nullpointer异常
