Force close onClick of ImageButton, can't figure out why
我正在尝试用ImageButtons做一个简单的动画,当我设置它时,如果我只是触摸屏幕,它工作得很好,但如果我尝试在onClick上做,应用程序就会关闭。
main.xml中
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center_horizontal"> <ImageButton android:id="@+id/plus1" android:layout_width="75dp" android:layout_height="75dp" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:background="@null" android:src="@drawable/plus" android:visibility="visible" android:gravity="center_horizontal" android:onClick="RunAnimations" /> <ImageButton android:id="@+id/gears1" android:layout_width="75dp" android:layout_height="75dp" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:background="@null" android:gravity="center_horizontal" android:src="@drawable/gears" android:textSize="42sp" /> </LinearLayout> |
translate.xml
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | <?xml version="1.0" encoding="utf-8"?> <set> <translate xmlns:android="http://schemas.android.com/apk/res/android" android:fromYDelta="-100%" android:toYDelta="0%" android:duration="1000" android:zAdjustment="top"> </translate> <alpha xmlns:android="http://schemas.android.com/apk/res/android" android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="1000"> </alpha> </set> |
主要活动:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | public class AnimationtestActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } private void RunAnimations() { Animation a = AnimationUtils.loadAnimation(this, R.anim.translate); View ib = findViewById(R.id.gears1); ib.clearAnimation(); ib.startAnimation(a); } } |
编辑:
我修好了
private void RunAnimations(查看视图)
但它仍然强行关闭

框架找不到您的单击处理程序方法,因为它具有错误的签名。 声明如下:
1 2 3 | public void RunAnimations(View view) { . . . } |
