Android的 - 动态滑动菜单 [英] Android - Dynamic Slide Menu
问题描述
使用教程（来源$ C $ C的这里），我是能够创造利用单一的XML布局菜单和主要内容都在Android上滑动菜单
问题是我需要做的菜单和内容的动态。我可以创建一个动态的观点，但我不知道如何用一个按钮\\轻扫切换到第二个动态视图或创建两种观点并有一个滑出时一键pressing。内容的必须的是动态的，菜单将在从互联网文件为主。我看过了无数的教程，但我还没有遇不到如何融合在一起所有的人都为单一的连贯的项目。
因此，这将意味着要么使视图菜单，查看上下文从上面链接（而不是从XML加载它），或简单地创建，我可以根据按键开关左右移动两种观点的来源$ C $ C动态。
下面的非动态版：

@覆盖
公共布尔onCreateOptionsMenu（菜单菜单）{
。getMenuInflater（）膨胀（R.menu.main，菜单）; 返回true;
}公共无效toggleMenu（视图v）{

}
}

开关（this.menuCurrentState）{
结案：
this.menu.setVisibility（View.VISIBLE）;
this.currentContentOffset = this.getMenuWidth（）;
this.context.offsetLeftAndRight（currentContentOffset）;
this.menuCurrentState = MenuState.Open;
打破;
开放的情况下：
this.context.offsetLeftAndRight（-currentContentOffset）;
this.currentContentOffset = 0;
this.menuCurrentState = MenuState.Closed;
this.menu.setVisibility（View.GONE）;
打破;
}
this.invalidate（）;
}私人诠释getMenuWidth（）{
返回this.menu.getLayoutParams（）宽。
}
私人无效calculateChildDimensions（）{
。this.context.getLayoutParams（）高度= this.getHeight（）;
。this.context.getLayoutParams（）宽度= this.getWidth（）; 。this.menu.getLayoutParams（）高度= this.getHeight（）;
。this.menu.getLayoutParams（）宽度= this.getWidth（） - menuMargin;
}
}
有已经可以使用一些好的库。无需推倒重来。
或者使用官方之一：
Using a tutorial (source code here), I was able to create a slide menu in android using a single xml layout for both the menu and the main content.
The problem is I need to make the menu and the content dynamic. I can create a dynamic view, but I don't know how to switch to a second dynamic view using a button\swipe or to create both views and have one slide out upon pressing of a button. The content must be dynamic, the menu will be based upon files from the internet. I've looked up numerous tutorials, but I haven't quite found how to meld all of them together into single coherent project.
So that would mean either making the View menu and View context dynamic from the source code linked above (rather than loading it from the xml), or simply creating two views that I can move around based on button switching.
Here's the non-dynamic version:
MainActivity.java
package com.example.slider;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import com.example.slider.view.viewgroup.FlyOutContainer;
public class MainActivity extends Activity{
FlyOutContainer root;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
this.root = (FlyOutContainer) this.getLayoutInflater().inflate(R.layout.activity_sample, null);
this.setContentView(root);
}
@Override
public boolean onCreateOptionsMenu(Menu menu){
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void toggleMenu(View v){
this.root.toggleMenu();
}
}
Here's FlyOutContainer.java
package com.example.slider.view.viewgroup;
import android.annotation.SuppressLint;
import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.ScrollView;
import android.widget.TextView;
@SuppressLint("NewApi")

private View menu;
private View context;
protected static final int menuMargin = 125;
public enum MenuState{

};

public FlyOutContainer(Context context, AttributeSet attrs, int defStyle) {

this.context = this.getChildAt(1);
this.menu.setVisibility(View.GONE);
}
protected void onLayout(boolean changed, int left, int top, int right, int bottom){
if(changed)
this.calculateChildDimensions();
this.menu.layout(left, top, right - menuMargin, bottom);
this.context.layout(left + this.currentContentOffset, top, right
+ currentContentOffset, bottom);
}
public void toggleMenu(){
switch(this.menuCurrentState){
case Closed:
this.menu.setVisibility(View.VISIBLE);
this.currentContentOffset = this.getMenuWidth();
this.context.offsetLeftAndRight(currentContentOffset);
this.menuCurrentState = MenuState.Open;
break;
case Open:
this.context.offsetLeftAndRight(-currentContentOffset);
this.currentContentOffset = 0;
this.menuCurrentState = MenuState.Closed;
this.menu.setVisibility(View.GONE);
break;
}
this.invalidate();
}
private int getMenuWidth(){
return this.menu.getLayoutParams().width;
}
private void calculateChildDimensions(){
this.context.getLayoutParams().height = this.getHeight();
this.context.getLayoutParams().width = this.getWidth();
this.menu.getLayoutParams().height = this.getHeight();
this.menu.getLayoutParams().width = this.getWidth() - menuMargin;
}
}
There are already some good libraries that you can use. No need to reinvent the wheel.
Or use the official one:
