错误：更新的Android Studio之后没有合适的构造从0.6.1至0.8.9 [英] Error: no suitable constructor after update Android Studio from 0.6.1 to 0.8.9
本文介绍了错误：更新的Android Studio之后没有合适的构造从0.6.1至0.8.9的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有这个错误：
Error:(78, 56) error: no suitable constructor found for ImageViewTouch(Viewpager_activity)
constructor ImageViewTouch.ImageViewTouch(Context,AttributeSet,int) is not applicable
(actual and formal argument lists differ in length)
constructor ImageViewTouch.ImageViewTouch(Context,AttributeSet) is not applicable
(actual and formal argument lists differ in length)
但这个错误我后，才更新的Android工作室出来后，从0.6.1到0.8.9，我没那个错误升级之前，事实上，code，我把下面的更新之前，完美地工作。
至多，我有对的Nexus 5的code中的应用，并没有任何问题。

该错误是在该行和列是有写本，就是ImageViewTouch语境中的：
The error is in this line and the column is where there is written "this", that is, the contex of ImageViewTouch:
final ImageViewTouch imageViewTouch = new ImageViewTouch(this);
我试过也是这些codeS：
I've tried also these codes:
final ImageViewTouch imageViewTouch = new ImageViewTouch(Viewpager_activity.this);
final ImageViewTouch imageViewTouch = new ImageViewTouch(getApplicationContext());
但它不会改变任何东西，我仍然得到这个错误
其他错误是这样的：
Error:(36, 41) error: no suitable constructor found for ImageViewTouch(Context)
constructor ImageViewTouch.ImageViewTouch(Context,AttributeSet,int) is not applicable
(actual and formal argument lists differ in length)
constructor ImageViewTouch.ImageViewTouch(Context,AttributeSet) is not applicable
(actual and formal argument lists differ in length)
和Java code是这个
And the java code is this
Viewpager_adapter.java
public class Viewpager_adapter extends PagerAdapter
{
private List<ImageViewTouch> imageViewTouches;
public Viewpager_adapter(List<ImageViewTouch> imageViewTouches)
{
this.imageViewTouches = imageViewTouches;
}
@Override
public int getCount() {
return imageViewTouches.size();
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
@Override
public Object instantiateItem(ViewGroup container, int position)
{
ImageViewTouch imageViewTouch = new ImageViewTouch(container.getContext());
imageViewTouch = (ImageViewTouch) imageViewTouches.get(position);
imageViewTouch.setScaleType(ImageViewTouch.ScaleType.MATRIX);
container.addView(imageViewTouch);
return imageViewTouch;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
ImageViewTouchViewPager pager = (ImageViewTouchViewPager) container;
View recycledView = (View) object;
pager.removeView(recycledView);
}
}
和错误的路线是这样的：
And the line of error is this:
ImageViewTouch imageViewTouch = new ImageViewTouch(container.getContext());
更具体而言，在code字符串的这一部分：
And more specifically , this part of the code string:
new ImageViewTouch(container.getContext());
的我更新Android工作室的一切工作顺利前重复。的
由于提前，如果你需要其他的codeS把它们
I repeat before updating Android Studio everything worked smoothly.
Thanks in advance, and if you need other codes put them
推荐答案
试试这个办法，希望这将帮助你解决你的问题。
在ImageViewTouch两级重载的构造函数定义如下：
In ImageViewTouch class two overloaded constructor define like :
ImageViewTouch(Context,AttributeSet) and ImageViewTouch(Context,AttributeSet,int)
和您正在尝试使用此构造中未ImageViewTouch类中定义初始化ImageViewTouch对象：
And your are trying to initialize ImageViewTouch object using this constructor which is not define in ImageViewTouch class:
ImageViewTouch(Context)
因此，尝试用一个重载的构造函数，如：
So try to use one overloaded constructor like :
new ImageViewTouch(container.getContext(),null,0) or new ImageViewTouch(container.getContext(),null)
在ViewPager喜欢的：
In ViewPager like :
ImageViewTouch imageViewTouch = new ImageViewTouch(container.getContext(),null); or ImageViewTouch imageViewTouch = new ImageViewTouch(container.getContext(),null,0);
这篇关于错误：更新的Android Studio之后没有合适的构造从0.6.1至0.8.9的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
