Question

我正在尝试将一个位于我的操作栏上的图像作为可点击的方式。我的意思是我想点击图片打开另一个课我该怎么办？

这是自定义操作栏，我以编程方式设置它。

ActionBar actionBar = getActionBar();
        actionBar.setDisplayOptions(actionBar.getDisplayOptions() | ActionBar.DISPLAY_SHOW_CUSTOM);
        ImageView imageView = new ImageView(actionBar.getThemedContext());
        imageView.setScaleType(ImageView.ScaleType.CENTER);
        imageView.setImageResource(R.drawable.logoonactionbar);
        ActionBar.LayoutParams layoutParams = new ActionBar.LayoutParams(ActionBar.LayoutParams.WRAP_CONTENT,  ActionBar.LayoutParams.WRAP_CONTENT, Gravity.END | Gravity.CENTER_VERTICAL);
        layoutParams.rightMargin = 20;
        imageView.setLayoutParams(layoutParams);
        actionBar.setCustomView(imageView);

        actionBar.setTitle(getResources().getString(R.string.secondaryView));

        getActionBar().setDisplayHomeAsUpEnabled(true);
        getActionBar().setHomeButtonEnabled(true);
        getActionBar().setIcon(android.R.color.transparent);
        getActionBar().setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.backgroundcolor)));

是否有可能，如果是这样，如何实现这一目标？

谢谢！

实际上非常简单只需在Menu.xml中添加项目即可这是menu.xml的示例代码

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Search, should appear as action button -->
<item android:id="@+id/action_search"
      android:icon="@drawable/ic_action_search"
      android:title="@string/action_search"
      android:showAsAction="ifRoom" />
<!-- Settings, should always be in the overflow -->
<item android:id="@+id/action_settings"
      android:title="@string/action_settings"
      android:showAsAction="never" />

使用此功能可以对这些按钮执行操作这是功能代码

@Override public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
    case R.id.action_search:
        openSearch(); //Any function call or anything you want to perform
        return true;
    case R.id.action_settings:
        openSettings(); //Any function call or anything you want to perform
        return true;
    default:
        return super.onOptionsItemSelected(item);
} }
