显示ProgressDialog时崩溃应用程序.我正在使用滑出式键盘在手机上进行测试.当显示对话框时,我滑动键盘和应用程序崩溃.

public static class ProgressDialogFragment extends DialogFragment
{

    public ProgressDialogFragment()
    {
        super();
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState)
    {
        final ProgressDialog dialog = new ProgressDialog(getActivity());
        dialog.setMessage(getString(R.string.dlg_progress_title));
        dialog.setIndeterminate(true);
        dialog.setCancelable(false);
        return dialog;
    }

    @Override
    public void show(FragmentManager manager, String tag)
    {
        try
        {
            super.show(manager, tag);
        }
        catch (IllegalStateException e)
        {
            Log.d(TAG, e.getMessage());
        }
    }

}

崩溃日志:

我创建了一个自定义视图并将其添加到布局:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        xmlns:custom="http://schemas.android.com/apk/res/com.eleks.customview"
        android:padding="20dp"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <com.eleks.customview.CView
            android:id="@+id/circle1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            custom:textSize="@dimen/circle_text_size"
            custom:text="@string/circle_default_text"
            custom:radius="@dimen/circle_radius"
            custom:textColor="@color/circle_text"
            custom:textBackground="@color/circle_background" />

    </LinearLayout>

我在自定义视图中实现onMeasure并设置宽度和高度.但是我的视图忽略了父填充(20dp).看图:

公共类CView扩展了View {private static final String TAG ="CView";

// default value
private static final int DEFAULT_RADIUS = 30;
private static final int DEFAULT_TEXT_SIZE = 12;
private static final int DEFAULT_TEXT_COLOR = Color.BLACK;
private static final int DEFAULT_BACKGROUND = Color.GRAY;
private static final int DEFAULT_WIDTH = DEFAULT_RADIUS * 2;
private static final int DEFAULT_HEIGHT = DEFAULT_RADIUS * 2;

// variables
private …

我不明白.如何在项目中添加和使用Espresso？

Espresso网址:https://code.google.com/p/android-test-kit/

如何将此库连接到我的项目？我想在Eclipse中有一个例子.

我需要在Android API中没有填充的GridView小于10.我的布局:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context=".MainActivity" >

<GridView
    android:id="@+id/grid"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:alwaysDrawnWithCache="true"
    android:background="@color/gridview_background"
    android:clipChildren="true"
    android:horizontalSpacing="1dp"
    android:numColumns="6"
    android:verticalSpacing="1dp" />

结果:

填充上显示红色箭头.它仅在Android <3.0中我需要的结果

没有填充物.

PS完全相同的Android 3.0上的代码没有填充.这是为什么？

我在Android中使用Espresso创建单元测试.我的项目有NavigationDrawer.我创建测试,必须滑动NavigationDrawer并单击按钮.在理解中,如何在我的测试中创建幻灯片操作.

我目前的解决方案

try
    {
        runTestOnUiThread(new Runnable()
        {

            @Override
            public void run()
            {
                DrawerLayout drawer = (DrawerLayout)getActivity().findViewById(R.id.drawer_layout);
                drawer.openDrawer(Gravity.LEFT);
            }
        });
    }
    catch (Throwable e)
    {
        e.printStackTrace();
    }

但我认为这是糟糕的代码.

我在资源中有字段(svn修订版).如何使用Gradle在我的领域中获得svn修订版,那不是用我的手来做的？
