TextView 中心重力崩溃

Question

嗨，我将背景设置为 textview

mImageAppInstallStatus.setBackgroundResource(R.drawable.downloaded);

然后我将textview的重力设置为中心如下

<TextView 
                    android:id="@+id/textview_price"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:textSize="12dp"
                    android:textColor="#ffffff"
                    android:gravity="center"
                    android:layout_alignParentLeft="true"/>

但在设备

 java.lang.StackOverflowError

Answer 1

您的 XML 可能太复杂了，提供额外的绘图命令可能会阻止您。

如果你有太多的嵌套布局视图，或者如果你有太多递归调用的方法，你会看到 java.lang.StackOverflowError 是很正常的。

查看Android Developers blog，了解如何理想地优化您的复杂布局。

另外不要忘记查看以下主题中关于嵌套布局数量的 CommonsWare 答案：
