Question

我正在尝试将clickListener添加到动态添加的LinearLayout内的ImageButton中，这是另一个（包装器）LinearLayout的一部分：

打包机：

   <LinearLayout
        android:id="@+id/persons_wrapper"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
    </LinearLayout>

将LinearLayout动态添加到上面的包装器中：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:custom="http://schemas.android.com/apk/res-auto"
    android:id="@+id/person_row"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal">

    <ImageButton
        android:id="@+id/share_with_person"
        android:src="@drawable/share_with"
        android:layout_weight="0"
        android:layout_marginTop="5dp"
        android:layout_width="35dp"

        android:layout_height="35dp"
        android:scaleType="fitCenter"
        android:layout_marginRight="5dp"
        />

    <TextView
        android:id="@+id/person_name"
        android:textColor="@color/secondary_text_color"
        android:hint="@string/person_name_hint"
        android:layout_marginTop="@dimen/margin_between_form_elements"
        android:layout_weight="1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/person_amount"
        android:textColor="@color/secondary_text_color"
        android:hint="10.20"
        android:layout_marginTop="@dimen/margin_between_form_elements"
        android:layout_weight="0"
        android:layout_width="90dp"
        android:layout_height="fill_parent" />
</LinearLayout>

用于在上面的布局中将clickListener添加到ImageButton的Java代码：

ViewGroup parentView = (ViewGroup) findViewById(R.id.persons_wrapper);

for (int i = 0; i < parentView.getChildCount(); i++) {
    //get the parent's childview, which is the linear layout wrapped around the name and amount for a person
    final View childView = parentView.getChildAt(i);
    Log.i("for loop", "looping");
    ImageButton shareWithPerson = (ImageButton) childView.findViewById(R.id.share_with_person);

    shareWithPerson.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Log.i("clicked", "share");


            shareTextWithChosenApp(childView);
        }
    });
    shareWithPerson.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View view) {
            Log.i("clicked", "long click");
            return false;
        }
    });

}

没有错误或者没有错，但是点击ImageButton之后根本没有任何反应。

我检查过的事情：

＆＃34;点击＆＃34;，＆＃34;循环＆＃34;已记录
parentView不是null childView和
shareWithPerson不为null，是所需的视图

提前致谢，

编辑：

shareTextWithChosenApp方法：

 private void shareTextWithChosenApp(View personRow) {
        Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
        sharingIntent.setType("text/plain");

        TextView personAmount = (TextView) personRow.findViewById(R.id.person_amount);
        String shareBody = personAmount.getText().toString();

        sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Rekening delen");
        sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);

        startActivity(Intent.createChooser(sharingIntent, "Delen met: "));

    }

在动态添加的LinearLayouts上放置onClickListeners
