Android的：如何传播点击事件的LinearLayout童车，改变他们绘制 [英] Android: How to propagate click event to LinearLayout childs and change their drawable

问题描述

我想创建一个将行为类似于ImageButton的线性布局。

I would like to create a linear layout which would behave similarly to ImageButton.

<LinearLayout
    android:id="@+id/container"
    style="?WidgetHomeIconContainer">            

    <ImageView
        android:id="@+id/icon"
        style="?WidgetHomeIcon" />

    <TextView
        android:id="@+id/title"
        style="?WidgetHomeLabel"             
        android:text="@string/title"
        android:textAppearance="?attr/TextHomeLabel" />
</LinearLayout>

在款式的ImageView，TextView的和的LinearLayout，我设置一个选择的所有状态。

In styles of ImageView, TextView and LinearLayout, I set a selectors for all states.

现在：

• 当我点击ImageView的（我想这也与ImageButton的） - 它行为正确的图像会根据选择的XML改变
。
• 当我点击的LinearLayout - 线性布局被点击，但ImageView的和TextView中不会改变它的绘制/外观

所以我想做到以下几点。当我点击父的LinearLayout，我需要改变一切的孩子的，以pressed状态。

So I would like to do the following. When I click on parent LinearLayout, I need to change all it's childs to pressed state.

我尝试添加以下code到的LinearLayout onClickListener传播点击：

I tried to add following code to LinearLayout onClickListener to propagate the click:

@Override
public void onClick(View v)
{
    LinearLayout l = (LinearLayout) v;
    for(int i = 0; i < l.getChildCount(); i++)
    {
        l.getChildAt(i).setClickable(true);
        l.getChildAt(i).performClick();
    }
}

但它仍然reamins相同。非常感谢您的任何帮助。

But it still reamins the same. Thank you very much for any help.

推荐答案

把

android:duplicateParentState="true"

在您的ImageView和TextView的.. <一href="http://developer.android.com/reference/android/view/View.html#attr_android%3aduplicateParentState">then意见从它的直接父，而不是从自身获得的绘制状态（pssed重点，$ P $等）。

in your ImageView and TextView..then the views get its drawable state (focused, pressed, etc.) from its direct parent rather than from itself.
