几个View的onTouch事件

来源：互联网发布：linux基础知识总结编辑：程序博客网时间：2024/04/30 09:20

类型一：（默认）

LayoutView1

public boolean onInterceptTouchEvent(MotionEvent ev) {
return super.onInterceptTouchEvent(ev);
}

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

LayoutView2

public boolean onInterceptTouchEvent(MotionEvent ev) {
return super.onInterceptTouchEvent(ev);
}

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

MyTextView

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

点击 MyTextView 运行Log：

04-04 03:31:11.349: I/LayoutView1(3639): +onInterceptTouchEvent()

04-04 03:31:11.359: I/LayoutView1(3639): onInterceptTouchEvent() action: ACTION_DOWN
04-04 03:31:11.359: I/LayoutView1(3639): -onInterceptTouchEvent() ,returnBoolean=false
04-04 03:31:11.359: D/LayoutView2(3639): +onInterceptTouchEvent()
04-04 03:31:11.369: D/LayoutView2(3639): onInterceptTouchEvent() action: ACTION_DOWN
04-04 03:31:11.369: D/LayoutView2(3639): -onInterceptTouchEvent() ,returnBoolean=false
04-04 03:31:11.369: W/MyTextView(3639): +onTouchEvent()
04-04 03:31:11.369: W/MyTextView(3639): onTouchEvent() action: ACTION_DOWN
04-04 03:31:11.379: W/MyTextView(3639): -onTouchEvent() returnBoolean =false
04-04 03:31:11.379: D/LayoutView2(3639): +onTouchEvent()
04-04 03:31:11.379: D/LayoutView2(3639): onTouchEvent() action: ACTION_DOWN
04-04 03:31:11.379: D/LayoutView2(3639): +onTouchEvent(),returnBlloean=false
04-04 03:31:11.379: I/LayoutView1(3639): +onTouchEvent()
04-04 03:31:11.379: I/LayoutView1(3639): onTouchEvent() action: ACTION_DOWN

04-04 03:31:11.379: I/LayoutView1(3639): +onTouchEvent(),returnBlloean=false

类型二：

LayoutView1

public boolean onInterceptTouchEvent(MotionEvent ev) {
return true;
}

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

LayoutView2

public boolean onInterceptTouchEvent(MotionEvent ev) {
return super.onInterceptTouchEvent(ev);
}

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

MyTextView

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

点击 MyTextView 运行Log：

04-04 03:42:10.029: I/LayoutView1(4213): +onInterceptTouchEvent()
04-04 03:42:10.029: I/LayoutView1(4213): onInterceptTouchEvent() action: ACTION_DOWN
04-04 03:42:10.029: I/LayoutView1(4213): -onInterceptTouchEvent() ,returnBoolean=true
04-04 03:42:10.029: I/LayoutView1(4213): +onTouchEvent()
04-04 03:42:10.039: I/LayoutView1(4213): onTouchEvent() action: ACTION_DOWN
04-04 03:42:10.039: I/LayoutView1(4213): +onTouchEvent(),returnBlloean=false

LayoutView1就直接消耗了，不向下分发了。

类型三：

LayoutView1

public boolean onInterceptTouchEvent(MotionEvent ev) {
return super.onInterceptTouchEvent(ev);
}

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

LayoutView2

public boolean onInterceptTouchEvent(MotionEvent ev) {
return true;
}

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

MyTextView

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

点击 MyTextView 运行Log：

04-04 03:47:23.129: I/LayoutView1(4598): +onInterceptTouchEvent()
04-04 03:47:23.139: I/LayoutView1(4598): onInterceptTouchEvent() action: ACTION_DOWN
04-04 03:47:23.149: I/LayoutView1(4598): -onInterceptTouchEvent() ,returnBoolean=false
04-04 03:47:23.149: D/LayoutView2(4598): +onInterceptTouchEvent()
04-04 03:47:23.149: D/LayoutView2(4598): onInterceptTouchEvent() action: ACTION_DOWN
04-04 03:47:23.149: D/LayoutView2(4598): -onInterceptTouchEvent() ,returnBoolean=true
04-04 03:47:23.149: D/LayoutView2(4598): +onTouchEvent()
04-04 03:47:23.159: D/LayoutView2(4598): onTouchEvent() action: ACTION_DOWN
04-04 03:47:23.159: D/LayoutView2(4598): +onTouchEvent(),returnBlloean=false
04-04 03:47:23.169: I/LayoutView1(4598): +onTouchEvent()
04-04 03:47:23.169: I/LayoutView1(4598): onTouchEvent() action: ACTION_DOWN
04-04 03:47:23.169: I/LayoutView1(4598): +onTouchEvent(),returnBlloean=false

即被LayoutView2消耗了，不向MyTextView分发

类型四：

LayoutView1

public boolean onInterceptTouchEvent(MotionEvent ev) {
return super.onInterceptTouchEvent(ev);
}

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

LayoutView2

public boolean onInterceptTouchEvent(MotionEvent ev) {
return super.onInterceptTouchEvent(ev);
}

public boolean onTouchEvent(MotionEvent event) {
return super.onTouchEvent(event);
}

MyTextView

public boolean onTouchEvent(MotionEvent event) {
return true;
}

点击 MyTextView 运行Log：

04-04 03:52:01.009: I/LayoutView1(4867): +onInterceptTouchEvent()
04-04 03:52:01.009: I/LayoutView1(4867): onInterceptTouchEvent() action: ACTION_DOWN
04-04 03:52:01.029: I/LayoutView1(4867): -onInterceptTouchEvent() ,returnBoolean=false
04-04 03:52:01.029: D/LayoutView2(4867): +onInterceptTouchEvent()
04-04 03:52:01.029: D/LayoutView2(4867): onInterceptTouchEvent() action: ACTION_DOWN
04-04 03:52:01.039: D/LayoutView2(4867): -onInterceptTouchEvent() ,returnBoolean=false
04-04 03:52:01.039: W/MyTextView(4867): +onTouchEvent()
04-04 03:52:01.039: W/MyTextView(4867): onTouchEvent() action: ACTION_DOWN
04-04 03:52:01.049: W/MyTextView(4867): -onTouchEvent() returnBoolean =true
04-04 03:52:01.149: I/LayoutView1(4867): +onInterceptTouchEvent()
04-04 03:52:01.149: I/LayoutView1(4867): onInterceptTouchEvent() action: ACTION_UP
04-04 03:52:01.149: I/LayoutView1(4867): -onInterceptTouchEvent() ,returnBoolean=false
04-04 03:52:01.199: D/LayoutView2(4867): +onInterceptTouchEvent()
04-04 03:52:01.199: D/LayoutView2(4867): onInterceptTouchEvent() action: ACTION_UP
04-04 03:52:01.199: D/LayoutView2(4867): -onInterceptTouchEvent() ,returnBoolean=false
04-04 03:52:01.209: W/MyTextView(4867): +onTouchEvent()
04-04 03:52:01.209: W/MyTextView(4867): onTouchEvent() action: ACTION_UP
04-04 03:52:01.209: W/MyTextView(4867): -onTouchEvent() returnBoolean =true

和类型一相比，Down被MyTextView消耗了，不会再向父容器传递了。父容器分发的UP事件也被消耗了

但是，试了很多次，好像UP事件没有像DOWN事件那样被向上传
