Question

在对话框中创建AutoCompleteTextView时遇到问题

我创建视图的代码是

private void setPalleteOnClicks() {
    ImageButton newMethod = (ImageButton) findViewById(R.id.new_method);
    newMethod.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            final Dialog dialog = new Dialog(AndroidPDStoreActivity.this);
            dialog.setContentView(R.layout.method_creation);
            dialog.setTitle("New Method Creator");

            //String[] types = {"int", "double"};
            ArrayAdapter<String> adapter = new ArrayAdapter<String>(AndroidPDStoreActivity.this,R.id.autoComplete, getResources().getStringArray(R.array.types));
            AutoCompleteTextView actv = (AutoCompleteTextView) dialog.findViewById(R.id.autoComplete);
            actv.setThreshold(1);
            actv.setAdapter(adapter);
            dialog.show();
        }

    });

}

我的Xml文件看起来像

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    .... 
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <TextView
            android:id="@+id/textView4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Return Type: "
            android:textAppearance="?android:attr/textAppearanceMedium" />

        <AutoCompleteTextView
            android:id="@+id/autoComplete"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:ems="10"
            android:dropDownHeight="100sp"
            android:text="" >

        </AutoCompleteTextView>

    </LinearLayout>

</LinearLayout>

我得到的例外是

我已尝试按照其他帖子的说明清理和删除R.java文件，但这没有帮助。只有在实际需要显示下拉菜单时才会出现此问题。

Answer 1

<强>问题：

new ArrayAdapter<String>(AndroidPDStoreActivity.this,R.id.autoComplete, getResources().getStringArray(R.array.types));

正如您可以在ArrayAdapter的构造函数中看到第二个参数，您正在xml中AutoCompleteTextView提供一个id Resources$NotFoundException。期望实例化视图的布局不是来自AutoCompleteTextView的id。

documentation：

The resource ID for a layout file containing a layout to use when instantiating views.

<强>溶液

你需要调用AutoCompleteTextView的原生android布局来用作实例化视图的布局。

<强>样品：

ArrayAdapter<String> adapter = new ArrayAdapter<String>(AndroidPDStoreActivity.this,
                        android.R.layout.simple_dropdown_item_1line,
                        getResources().getStringArray(R.array.types));

Answer 2

这是与您拥有layout-[qualifier]个文件夹的多个屏幕尺寸相关的问题吗？您可能会遇到一个屏幕尺寸的资源，而另一个屏幕尺寸则没有。如果是，您可能希望将一些布局（根据屏幕大小不会更改的布局）移动到不合格的layout文件夹，而不是将其保留在特定的基于大小的文件夹中。
