这是我的代码的简短版本。
当我跑步并且只触摸第二个视图时，日志是：
imageanswer setontouchlistener
imageanswer setontouchlistener actiondown
imageanswer setontouchlistener
imageanswer setontouchlistener else
它甚至不会调用拖动。它不能进入阻力。
我试图让这个类扩展活动但没有改变。
以前，为了测试我创建了不同的类，它正在工作。不同之处在于，imageview位置是静态的，我在oncreate中完成所有操作。
这是有效的：
public class MainActivity extends Activity implements View.OnDragListener {
private ImageView img1, img2, img3;
String TAG = "Chic";
private Button btn,item;
@Override
protected void onCreate(Bundle savedInstanceState) {
Log.d(TAG, "oncreate start");
super.onCreate(savedInstanceState);
setContentView(R.layout.main_lands);
img1 = (ImageView) findViewById(R.id.img1);
//img1.setOnLongClickListener(this);
img2 = (ImageView) findViewById(R.id.img2);
// img2.setOnLongClickListener(this);
img3 = (ImageView) findViewById(R.id.img3);
// img3.setOnLongClickListener(this);
img1.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
ClipData data = ClipData.newPlainText("", "");
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v);
v.startDrag(data, shadowBuilder, v, 0);
v.setVisibility(View.INVISIBLE);
return true;
} else {
return false;
}
}
});
img2.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
ClipData data = ClipData.newPlainText("", "");
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v);
v.startDrag(data, shadowBuilder, v, 0);
v.setVisibility(View.INVISIBLE);
return true;
} else {
return false;
}
}
});
img3.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
ClipData data = ClipData.newPlainText("", "");
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v);
v.startDrag(data, shadowBuilder, v, 0);
v.setVisibility(View.INVISIBLE);
return true;
} else {
return false;
}
}
});
img1.setOnDragListener(this);
img2.setOnDragListener(this);
img3.setOnDragListener(this);
public boolean onTouch(View view, MotionEvent motionEvent) {
Log.d(TAG, "ontouch never");
if (motionEvent.getAction() == MotionEvent.ACTION_DOWN) {
ClipData data = ClipData.newPlainText("", "");
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(view);
view.startDrag(data, shadowBuilder, view, 0);
view.setVisibility(View.INVISIBLE);
return true;
} else {
return false;
}
}
public boolean onDrag(View receivingLayoutView, DragEvent dragEvent) {
Log.d(TAG, "ondrag start");
//and so on
.
.
有什么区别，为什么这个工作和我的不相同？
当我在一个线程内运行它时，我的类也可以运行，在oncreate中：
Thread t = new Thread() {
@Override
public void run() {
imageAnswer.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) { Log.d(TAG,"6isanswered : "+isAnswered);
Log.d(TAG,"matchinggame setontouch");
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Log.d(TAG,"matchinggame setontouch if yes");
ClipData data = ClipData.newPlainText("", "");
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v);
v.startDrag(data, shadowBuilder, v, 0);
v.setVisibility(View.INVISIBLE); Log.d(TAG,"7isanswered : "+isAnswered);
return true;
} else { Log.d(TAG,"8isanswered : "+isAnswered);
return false;
}
}
});
imageAnswer.setOnDragListener(MatchingGame.this);
Log.d(TAG,"*");
区别是因为它是线程，我不使用this，我使用matchingame.this
我无法弄明白。
这是我的布局：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
android:id="@+id/relative_layout"
tools:context=".games.MatchingGame">
</RelativeLayout>
我使用相同的方法和构造来点击事件，它很好用。但为什么不拖延？
当我触摸图像并离开时，它会永远消失。
在动态中，例如当我放到某个地方时，在日志中它说：
"Drag is in progress but there is no drag window handle."
但不在我的标签中，因为w，警告。
使用相同的代码，当我跌落到空的地方时，它会再次变得可见但是当我跌落时它会立即消失。
我看了所有这些 https://www.google.com.tr/search?q=%22%22Drag+is+in+progress+but+there+is+no+drag+window+handle.%22%22&oq=%22%22Drag+is+in+progress+but+there+is+no+drag+window+handle.%22%22&aqs=chrome..69i57.1353j0j9&sourceid=chrome&ie=UTF-8但它们不同并且无效。
我不知道原因，我猜是因为我使用动态图片添加。
这是ids
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item name="refresh" type="id"/>
<item name="settings" type="id"/>
<item name="imgAnswer" type="id"/>
我也试过那些但没有用的
imageAnswer = new ImageView(this);
imageAnswer.setImageBitmap(bmp);
imageAnswer.setTag(trainingObject.getTrainingobjectAnswer());
//imageAnswer.findViewById(R.id.imgAnswer);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
rLayout.generateViewId();
imageAnswer.setId(R.id.imgAnswer);
}
rLayout.removeAllViews();
rLayout.addView(imageAnswer,rLayParams);
View.generateViewId();
imageAnswer.setId(R.id.imgAnswer);
View.generateViewId();
rLayout.setId(R.id.imgAnswer);
我尝试了所有。
修改
当我尝试shando的建议时，我的日志是：
imageanswer setontouchlistener
imageanswer setontouchlistener actiondown
parent android.widget.RelativeLayout{bcd0e74 V.E...... ........ 0,0-320,186 #7f0c0058 app:id/relative_layout}

imageanswer setontouchlistener
ontouch else
android.widget.RelativeLayout{bcd0e74 V.E...... ......ID 0,0-320,186 #7f0c0058 app:id/relative_layout}

view android.widget.ImageView{26eaf9d I.ED..... ........ 12,86-26,100 #1}
我的代码是这样的，我在api 23模拟器上：
/* imageAnswer = new ImageView(this);
imageAnswer.setImageBitmap(bmp);
imageAnswer.setTag(trainingObject.getTrainingobjectAnswer());
imageAnswer.findViewById(R.id.imgAnswer);*/
int idThatCanBeUsedLater = R.id.imgAnswer;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN_MR1) { Log.d(TAG,"if");
idThatCanBeUsedLater = View.generateViewId();}
imageAnswer = new ImageView(this);
imageAnswer.setId(idThatCanBeUsedLater);
imageAnswer.setTag(trainingObject.getTrainingobjectAnswer());
imageAnswer.setImageBitmap(bmp);
rLayout.removeAllViews();
rLayout.addView(imageAnswer,rLayParams);
imageAnswer.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
imageAnswer.getParent().requestDisallowInterceptTouchEvent(true);
Log.d(TAG,"imageanswer setontouchlistener");
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Log.d(TAG,"imageanswer setontouchlistener actiondown");
Log.d(TAG,"parent "+ String.valueOf(imageAnswer.getParent()));
Log.d(TAG, "view "+String.valueOf(v));
ClipData data = ClipData.newPlainText("", "");
// Log.d(TAG,"data: "+data.toString());
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v);
v.startDrag(data, shadowBuilder, v, 0);
v.setVisibility(View.INVISIBLE);
return true;
} else {
Log.d(TAG, "ontouch else");
Log.d(TAG, String.valueOf(imageAnswer.getParent()));
Log.d(TAG,"imageanswer setontouchlistener else: "+event.toString());
Log.d(TAG,"view "+ String.valueOf(v));
if (event.getAction() == MotionEvent.ACTION_CANCEL) {
ClipData data = ClipData.newPlainText("", "");
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v);
v.startDrag(data, shadowBuilder, v, 0);
v.setVisibility(View.INVISIBLE);
return true;}
return false;
}
}
});
imageAnswer.setOnDragListener(this);
这是完整代码

我认为您的问题是，在初始化onDrag时，您将设置为隐藏您的视图：
ClipData data = ClipData.newPlainText("", "");
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v);
v.startDrag(data, shadowBuilder, v, 0);
v.setVisibility(View.INVISIBLE); Log.d(TAG,"7isanswered : "+isAnswered);
return true;
另一方面，为什么使用setOnTouchListener代替setOnClickListener？对于这种情况，我认为这不是最好的主意。
最后，我想您没有在onDrag中显示所有代码，因为它看起来完全是空的。但是，你必须在Switch内部的每个案例中返回true以继续下一个（并在ACTION_DRAG_ENDED中返回false）
所以你的onDrag需要像：
//Your code
imageAnswer.setOnDragListener(this);
imageAnswer.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
ClipData data = ClipData.newPlainText("", "");
View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v);
v.startDrag(data, shadowBuilder, v, 0);
v.setVisibility(View.INVISIBLE); Log.d(TAG,"7isanswered : "+isAnswered);
return true;
}
});
rLayout.removeAllViews();
rLayout.addView(imageAnswer,rLayParams);
}
Override
public boolean onDrag(View receivingLayoutView, DragEvent dragEvent) {
Log.d(TAG, "ondrag start");
switch (dragEvent.getAction()) {
case DragEvent.ACTION_DRAG_STARTED:
//Do something
return true;
case DragEvent.ACTION_DRAG_ENTERED:
//Do something
return true;
case DragEvent.ACTION_DRAG_LOCATION:
//Do something
return true;
case DragEvent.ACTION_DRAG_EXITED:
//Do something
return true;
case DragEvent.ACTION_DROP:
//Do something
return true;
case DragEvent.ACTION_DRAG_ENDED:
//Do something
return false;
}

您在代码中设置了视图ID。你能删除imageAnswer.setId（R.id.imgAnswer）;或者，如果您使用min SDK 17将其替换为generateViewId。可能是潜在重复ID内的问题。
