Android开发之自定义ActionBar和TitleBar

首先给出代码和效果

private void configureActionBar() {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View customActionBarView = inflater.inflate(R.layout.call_log_multiple_delete_custom_action_bar, null);

ImageButton doneMenuItem = (ImageButton) customActionBarView.findViewById(R.id.done_menu_item);
doneMenuItem.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v){
finish();
}
});
Button selectView = (Button) customActionBarView.findViewById(R.id.select_items);
selectView.setBackgroundDrawable(getResources().getDrawable(
R.drawable.dropdown_normal_holo_dark));
selectView.setOnClickListener(new OnClickListener() {
new OnClickListener() {
@Override
public void onClick(View v){
updateSelectionMenu(parent);
mSelectionMenu.show();
}
});
Button cancelView = (Button) customActionBarView
.findViewById(R.id.cancel);
String cancelText = cancelView.getText().toString();
if ("Cancel".equalsIgnoreCase(cancelText)) {
cancelText = cancelText.toUpperCase();
cancelView.setText(cancelText);
}
ActionBar actionBar = getActionBar();
if (actionBar != null) {
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM,
ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_SHOW_HOME
| ActionBar.DISPLAY_SHOW_TITLE);
actionBar.setCustomView(customActionBarView);

下面给出部分.xml 文件
