Replace your shakeanim.xml file with this.
用这个替换你的 Shakeanim.xml 文件。
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:duration="150"
android:fromXDelta="-10%"
android:repeatCount="5"
android:repeatMode="reverse"
android:toXDelta="10%"/>
</set>
btw you can change your MainActivity "setOnClickListener" like this as you have already declared imageButton.
顺便说一句，您可以像这样更改 MainActivity“setOnClickListener”，因为您已经声明了 imageButton。
imageButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
clicks--;
clicksToGo.setText("You need to click " + clicks + " more times to open it");
imageButton.startAnimation(shake);
}
});
If this helps please mark it as the right answer. Thank you
