ListView 内EditText 的LayoutParams 无法正常工作，无法在edittext 中键入任何字符

Question

我有一个 list.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.phongponix.trackingbodybuilding.MainActivity$PlaceholderFragment"
    android:orientation="vertical"
    >

    <ListView android:id="@+id/lvExerciseList"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clipToPadding="false"
        android:paddingBottom="50dp"
       ></ListView>
</LinearLayout>

我的 list_item.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:padding="20dp"
    android:id="@+id/containerTest">


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

        <ImageView
            android:id="@+id/imgExcercisePhoto"
            android:layout_width="100dp"
            android:layout_height="100dp" />

        <TextView
            android:id="@+id/tvExerciseName"
            android:layout_width="100dp"
            android:layout_height="wrap_content"
            android:text="aaa" />
    </LinearLayout>
    <RelativeLayout android:id="@+id/rlRecordContainer"
        android:layout_width="150dp"
        android:layout_height="match_parent"
        android:orientation="horizontal">

    </RelativeLayout>


    <android.support.v7.widget.RecyclerView
        android:id="@+id/rvExcerciseRecords"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_toRightOf="@id/first_panel"
        android:clipToPadding="false"
        android:scrollbars="horizontal"></android.support.v7.widget.RecyclerView>

</LinearLayout>

我将适配器用于我的列表，如下所示：

if (convertView == null) {
            view = inflater.inflate(R.layout.list_item, null);
            viewHolder = new ViewHolder();
            viewHolder.title = (TextView) view.findViewById(R.id.tvExerciseName);
            view.setTag(viewHolder);
            LinearLayout container = (LinearLayout)view.findViewById(R.id.first_panel);

            LinearLayout.LayoutParams layoutParamsWeight = new LinearLayout.LayoutParams(convertDpToPixel(activity, 30), convertDpToPixel(activity, 20));
            layoutParamsWeight.setMargins(0, 0, convertDpToPixel(activity, 5), convertDpToPixel(activity, 5));
            EditText etWeight = new EditText(activity);
            etWeight.setWidth(convertDpToPixel(activity, 30));
            etWeight.setHeight(convertDpToPixel(activity, 20));
            //etWeight.setLayoutParams(layoutParamsWeight);
            etWeight.setBackgroundColor(ContextCompat.getColor(activity, R.color.colorEditTextBox));
            etWeight.setInputType(InputType.TYPE_CLASS_NUMBER);
            etWeight.setFocusableInTouchMode(true);
            //etWeight.setId(currentWeightID);
            container.addView(etWeight);

            RelativeLayout relativeLayout = (RelativeLayout) view.findViewById(R.id.rlRecordContainer);
            renderRecordItemHead(activity, relativeLayout);
            renderRecordItem(activity, relativeLayout, currentWeightID);

            recyclerView = (RecyclerView) view.findViewById(R.id.rvExcerciseRecords);
            LinearLayoutManager linearLayoutManager = new LinearLayoutManager(activity, LinearLayoutManager.HORIZONTAL, false);
            linearLayoutManager.setStackFromEnd(true);
            recyclerView.setLayoutManager(linearLayoutManager);
            recyclerView.setAdapter(trackingPlanHorizontalAdapter);


        }

如下图所示，如果我注释掉（不使用）LayoutParams，我可以输入并查看我的 EditText 中的字符。如果我为 EditText 使用 LayoutParams，我无法输入。当我点击 EditText 时，键盘出现，然后它失去焦点，所以每当我触摸键盘时，它什么都不显示。

几天前我也遇到了同样的问题。但显然它实际上正在被编辑，但由于 EditText 的默认填充和文本大小，它不适合我提供的 layoutparams 并且它正在裁剪额外的部分，所以它对我来说是不可见的。尝试将 textsize 设置为小并填充 0。它会起作用

为什么不在 XML 中使用 edittext 视图？

<EditText
android:id = @+id/"edit_ text"
android:text = "Edit text here"
android:layout_width = 100dp
android:layout_height = 100dp
