父活动的code得到执行，但结果（动画）没有显示出来 [英] Parent Activity's code getting executed, but the result (animation) is not showing up
问题描述
我想有我的整个应用程序中的滑动菜单，这将是在我的应用程序的每个活动进行访问。对于这一点，我创建了一个父活动，而所有其他活动扩展为在这个答案建议。这样，只有一个活动将实现滑动菜单功能和扩展该活动的所有其他活动将有落实。但我的问题是，当我preSS按钮（应用程序图标）的滑动抽屉应该出现了，整个布局应该转移到右侧。这工作正常的BaseActivity，但对于活动的扩展这个类，它不工作。无论抽屉越来越显示，也没有布局转向右侧。我试图把在BaseActivity的适当的方法烤面包，面包越来越显示，但是抽屉没有显示出来。可能是什么问题？
布局XML如下，
＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT; RelativeLayout的

机器人：ID =@ + ID / rl_root

＆LT; RelativeLayout的

机器人：layout_height =FILL_PARENT
机器人：背景=@色/ menu_bg
机器人：方向=垂直

滑动抽屉放在这里。

＆LT; / RelativeLayout的＆GT;
＆LT;！ - 下面是实际的布局，其中在从事其他活动的布局
将投入使用下面的Java code。 - ＆GT;

和重写的的setContentView（）方法如下：
@覆盖
公共无效的setContentView（INT layoutResID）{
_completeLayout =（RelativeLayout的）getLayoutInflater（）膨胀（R.layout.menu，空）。
_activityLayout =（RelativeLayout的）_completeLayout.findViewById（R.id.rl_right）;
。getLayoutInflater（）膨胀（layoutResID，_activityLayout，真正的）;
的setContentView（_completeLayout）;
}
在点击操作栏上按钮的，下面code在 BaseActivity
@覆盖
公共布尔onOptionsItemSelected（菜单项项）{
开关（item.getItemId（））{
案例android.R.id.home：
_leftLayout.setVisibility（View.VISIBLE）;
INT宽度= _leftLayout.getWidth（）;
如果（宽== 0）{
宽= 300;
}
如果（！isMenuVisible（））{
Toast.makeText（这一点，成功运行了......，Toast.LENGTH_LONG）.show（）;
_leftLayout.setVisibility（View.VISIBLE）;
_rightLayoutParams =新的LayoutParams（
_rightLayout.getWidth（），_rightLayout.getHeight（））;
_rightLayoutParams.setMargins（宽度，0， - 宽度，0）;
_rightLayout.setLayoutParams（_rightLayoutParams）;
动画slideRight = setRightSlidingAnimation（）;
_leftLayout.startAnimation（slideRight）;
_rightLayout.startAnimation（slideRight）;
} 其他 {
动画slideLeft = setLeftSlidingAnimation（）;
_rightLayout.startAnimation（slideLeft）;
_leftLayout.startAnimation（slideLeft）;
}
setMenuVisible（isMenuVisible（）！）;
打破;
}
返回false;
}
问题解决了，只是要在 onOptionsItemSelected 再次初始化视图，因为正确的布局已经改变。该方法现在看起来像：
@覆盖
公共布尔onOptionsItemSelected（菜单项项）{
开关（item.getItemId（））{
案例android.R.id.home：
_rootLayout =（RelativeLayout的）findViewById（R.id.rl_root）;
_leftLayout =（RelativeLayout的）findViewById（R.id.ll_lhs_menu）;
_rightLayout =（RelativeLayout的）findViewById（R.id.rl_right）;
_leftLayout.setVisibility（View.VISIBLE）;
INT宽度= _leftLayout.getWidth（）;
如果（宽== 0）{
宽= 300;
}
如果（！isMenuVisible（））{
Toast.makeText（这一点，成功运行了......，Toast.LENGTH_LONG）.show（）;
_leftLayout.setVisibility（View.VISIBLE）;
_rightLayoutParams =新的LayoutParams（
_rightLayout.getWidth（），_rightLayout.getHeight（））;
_rightLayoutParams.setMargins（宽度，0， - 宽度，0）;
_rightLayout.setLayoutParams（_rightLayoutParams）;
动画slideRight = setRightSlidingAnimation（）;
_leftLayout.startAnimation（slideRight）;
_rightLayout.startAnimation（slideRight）;
} 其他 {
动画slideLeft = setLeftSlidingAnimation（）;
_rightLayout.startAnimation（slideLeft）;
_leftLayout.startAnimation（slideLeft）;
}
setMenuVisible（isMenuVisible（）！）;
打破;
}
返回false;
}
I want to have a sliding menu throughout my application which will be accessible for every activity in my application. For this, I created a parent activity to which all other activities extend as suggested in this answer. So that, only one activity will implement that sliding menu functionality and all other activities extending that activity will have that implementation. But my problem is, when I press UP button (app icon) the sliding drawer should show up and the whole layout should shift to the right side. This works fine for the BaseActivity, but for the activities extending that class, its not working. Neither the drawer is getting shown, nor the layout is shifting towards right. I tried putting toasts in the BaseActivity's appropriate method, the Toast is getting shown but the drawer is not showing up. What can be the problem?
The layout xml is as follows,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rl_root"
android:layout_width="wrap_content"
android:layout_height="fill_parent" >
<RelativeLayout
android:id="@+id/ll_lhs_menu"
android:layout_width="300dip"
android:layout_height="fill_parent"
android:background="@color/menu_bg"
android:orientation="vertical"
android:visibility="visible" >
.......
Sliding drawer goes here.
.......
</RelativeLayout>
<!-- Following is the actual layout where in the layout for other activities
will be put in using the java code below. -->
<RelativeLayout
android:id="@+id/rl_right"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:background="@drawable/capture_port"
android:scrollbars="none" >
</RelativeLayout>
</RelativeLayout>
And the overridden setContentView() method is as follows:
@Override
public void setContentView(int layoutResID) {
_completeLayout= (RelativeLayout) getLayoutInflater().inflate(R.layout.menu, null);
_activityLayout= (RelativeLayout) _completeLayout.findViewById(R.id.rl_right);
getLayoutInflater().inflate(layoutResID, _activityLayout, true);
setContentView(_completeLayout);
}
On click of UP button on action bar, following code is executed in BaseActivity
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
_leftLayout.setVisibility(View.VISIBLE);
int width = _leftLayout.getWidth();
if (width == 0) {
width = 300;
}
if (!isMenuVisible()) {
Toast.makeText(this, "Executed successfully...", Toast.LENGTH_LONG).show();
_leftLayout.setVisibility(View.VISIBLE);
_rightLayoutParams = new LayoutParams(
_rightLayout.getWidth(), _rightLayout.getHeight());
_rightLayoutParams.setMargins(width, 0, -width, 0);
_rightLayout.setLayoutParams(_rightLayoutParams);
Animation slideRight = setRightSlidingAnimation();
_leftLayout.startAnimation(slideRight);
_rightLayout.startAnimation(slideRight);
} else {
Animation slideLeft = setLeftSlidingAnimation();
_rightLayout.startAnimation(slideLeft);
_leftLayout.startAnimation(slideLeft);
}
setMenuVisible(!isMenuVisible());
break;
}
return false;
}
Problem solved, just had to initialize the view once again in onOptionsItemSelected since the right layout has changed now. The method now looks like:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
_rootLayout = (RelativeLayout) findViewById(R.id.rl_root);
_leftLayout = (RelativeLayout) findViewById(R.id.ll_lhs_menu);
_rightLayout = (RelativeLayout) findViewById(R.id.rl_right);
_leftLayout.setVisibility(View.VISIBLE);
int width = _leftLayout.getWidth();
if (width == 0) {
width = 300;
}
if (!isMenuVisible()) {
Toast.makeText(this, "Executed successfully...", Toast.LENGTH_LONG).show();
_leftLayout.setVisibility(View.VISIBLE);
_rightLayoutParams = new LayoutParams(
_rightLayout.getWidth(), _rightLayout.getHeight());
_rightLayoutParams.setMargins(width, 0, -width, 0);
_rightLayout.setLayoutParams(_rightLayoutParams);
Animation slideRight = setRightSlidingAnimation();
_leftLayout.startAnimation(slideRight);
_rightLayout.startAnimation(slideRight);
} else {
Animation slideLeft = setLeftSlidingAnimation();
_rightLayout.startAnimation(slideLeft);
_leftLayout.startAnimation(slideLeft);
}
setMenuVisible(!isMenuVisible());
break;
}
return false;
}
