我发现，当我创建一个布局和Java文件时，我正在编写代码，所以当我按下按钮时，它会转到另一个活动。
我已经调用了9个方法将我发送到另一个活动，MainJava类中有3个或4个，布局中有4个，一切正常。
但现在新按钮中的1个按钮不起作用，并说“遗憾的是应用程序停止了”。我无法弄清楚真正的问题在哪里，但代码就像其他按钮一样，效果很好。

我点击了onClick按钮：

android:layout_below="@+id/line1"
android:layout_toLeftOf="@+id/textView45"
android:layout_toStartOf="@+id/textView45" />
</RelativeLayout>
当然我在Java文件中创建一个命令：
public void sendPhone(View view) {
Intent intent = new Intent(getApplicationContext(), phoneclass.class);
startActivity(intent);
}
我创建清单文件：
activity android:name=".phoneclass">
正如我之前所说的，其他9个按钮运行良好，但有一个按钮正在变：“不幸的是，应用程序停止工作”。

这真是奇怪的事情，一切正常，但是那1个按钮。
问题隐藏的任何想法？
答案 0 :(得分：0)
当我跟踪你的logcat时，它告诉错误似乎是由内存不足引起的，这通常会在你有大尺寸图像时发生。如果这可能对您有所帮助，请尝试查看此链接。 App crashes on change of ImageView
此外，您使用的是实际设备还是模拟器？如果您使用的是模拟器，请尝试增加大小分配。如果您有可以测试的设备，请尝试并检查您是否会遇到同样的问题。
答案 1 :(得分：0)
我认为你的布局文件中有大尺寸的图像导致了OutOfMemoryError。正如Android培训指南所述
如果您不小心，位图可以快速消耗您的可用 内存预算导致应用程序因可怕而崩溃 exception：java.lang.OutofMemoryError：位图大小超过VM预算。
您可以按照以下课程尝试有效加载图片
Displaying Bitmaps Efficiently
SO中有一些很好的解决方案来解决这些问题。
Out of memory error when inflating simple xml layout in android
答案 2 :(得分：-2)
尝试在Intent intent = new Intent(this, phoneclass.class);
