请帮我。我对自定义视图有疑问。如果我的 customview 中的文本太长，并且显示 ProgressBarIndeterminate，则应用程序崩溃。这是活动中的 onCreateOptionsMenu：

public boolean onCreateOptionsMenu(Menu menu) {
    toggle();
    this.getMenuInflater().inflate(R.menu.main, menu);
    actionBar = getActionBar();
    actionBar.setDisplayUseLogoEnabled(false);
    actionBar.setDisplayShowTitleEnabled(false);
    actionBar.setDisplayShowHomeEnabled(false);
    actionBar.setDisplayOptions(0, ActionBar.DISPLAY_SHOW_TITLE);
    actionBar.setDisplayOptions(0, ActionBar.DISPLAY_SHOW_HOME);
    actionBar.setDisplayOptions(0, ActionBar.DISPLAY_USE_LOGO);
    actionBar.setDisplayOptions(0, ActionBar.DISPLAY_HOME_AS_UP);
    View customView = getLayoutInflater().inflate(
            R.layout.action_bar_display_options_custom, null);
    customView.findViewById(R.id.action_home).setOnClickListener(
            new OnClickListener() {

                @Override
                public void onClick(View v) {
                    toggle();
                }
            });
    btnSort = customView.findViewById(R.id.sort_view);
    btnSort.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            onPopupButtonClick(v);
        }
    });
    txtTitle = (TextView) customView.findViewById(R.id.action_title);
    actionBar.setCustomView(customView, new ActionBar.LayoutParams(
            LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
    actionBar.setDisplayShowCustomEnabled(true);
    // search button
    searchButton = (SearchView) menu.findItem(R.id.action_search)
            .getActionView();
    searchButton.setOnQueryTextListener(this);
    // set title on first
    refreshTitleBar();
    return true;
}

这是自定义视图布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:orientation="horizontal" >

<ImageView
    android:id="@+id/action_home"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:scaleType="fitStart"
    android:src="@drawable/btn_home" />

<LinearLayout
    android:id="@+id/sort_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_vertical" >

    <TextView
        android:id="@+id/action_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ellipsize="start"
        android:maxLines="1"
        android:textColor="@android:color/white" />

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="5dp"
        android:src="@drawable/sort_icon" />
</LinearLayout></LinearLayout>

如果我设置的标题太长，“setProgressBarIndeterminateVisibility”方法会使应用程序崩溃。这是我的 LogCat 输出。

是的，您的问题android:ellipsize="start"与 Crazy 相结合，android:maxLines="1"即使在 Lollipop 上仍然存在此错误。解决方案也是设置android:singleLine="true"，尽管它已被弃用似乎可以解决问题。
