删除自定义选项菜单项之间的行

时间：2012-05-13 17:55:49

标签： android

我自定义了选项菜单，删除了默认背景并通过引用样式自定义了它自己的项目，但我在图片中所示的项目之间的行中删除。

任何建议都将受到赞赏。

我的代码：

   <shape xmlns:android="http://schemas.android.com/apk/res/android"
     android:shape="rectangle">
      <stroke android:width="1dp" android:height="1dp" android:color="#B22222" /> 
   <solid android:color="#FCE6C9" /> 
     <padding android:left="2dp" android:top="2dp" android:right="2dp"
          android:bottom="2dp" /> 
   <corners  android:bottomRightRadius="30dp"  android:bottomLeftRadius="30dp"
     android:topLeftRadius="30dp"  android:topRightRadius="30dp" />

    </shape>

选项菜单代码：

  public class OptionMenu extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);}

public boolean onCreateOptionsMenu(android.view.Menu menu) {

    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.cool_menu, menu);

    getLayoutInflater().setFactory(new Factory() {
    public View onCreateView(String name, Context context,
    AttributeSet attrs) {

    if (name .equalsIgnoreCase("com.android.internal.view.menu.IconMenuItemView")) {
    try {

    LayoutInflater li = LayoutInflater.from(context);
    final View view = li.createView(name, null, attrs);

    new Handler().post(new Runnable() {
    public void run() {

    // set the background drawable
    view .setBackgroundResource(R.drawable.border);

    ((TextView) view).setTextSize(20); 

    // set the text color
    ((TextView) view).setTextColor(Color.RED);}
        });
    return view;}
     catch (InflateException e) { }
     catch (ClassNotFoundException e) { }
            }
    return null; }
            });
    return super.onCreateOptionsMenu(menu);}


    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // TODO Auto-generated method stub
        switch (item.getItemId()) {
        case R.id.AboutUs:
            Intent i = new Intent("com.test.demo.ABOUT");
            startActivity(i);

             break;
                 case R.id.preferences:
                 Intent p = new Intent("com.test.demo.PREFS");
                 startActivity(p);
             break;
             case R.id.exit:
                   finish();
             break;}
            return false;} }

cool_menu.xml：

<?xml version="1.0" encoding="utf-8"?>
 <menu xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:title="about"  android:id="@+id/AboutUs"  /> 
 <item android:title="Prefs"  android:id="@+id/preferences" /> 
 <item android:title="Exit"   android:id="@+id/exit" /> 
 </menu>

menu_style.xml：

 <?xml version="1.0" encoding="utf-8"?>
     <resources>
        <style name="Theme_menu">
        <item name="android:panelFullBackground">@drawable/border</item> 
          </style>
     </resources>

将清单中的样式推荐给选项菜单：

  <activity
           android:name=".OptionMenu"
           android:label="@string/app_name" android:theme="@style/Theme_menu">

正如您所提到的，您希望找到一种删除线的解决方案。我不知道这样做但我也喜欢编写自己的动态和可定制的菜单系统（特别是在动画和图形中）。您可以选择为我自己的项目编写的源代码。

根据需要设计你的布局。

下一步

答案 1 :(得分：2)

这些分隔符看起来类似于默认情况下在ListView中的条目之间插入的分隔符。根据菜单与ListView的相似程度（可能不是很多），以下代码修改可能有效：

<?xml version="1.0" encoding="utf-8"?>
<menu 
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:divider="@android:color/transparent">

   <item android:title="about"  android:id="@+id/AboutUs"  /> 
   <item android:title="Prefs"  android:id="@+id/preferences" /> 
   <item android:title="Exit"   android:id="@+id/exit" /> 
</menu>

如果这不起作用，那么阅读Menu object可能会有用。我在Menu.addIntentOptions()函数文档中找到了以下引用。

  

通常，此功能会自动删除同一组菜单中的所有现有项目，并在添加的项目上方和下方放置一个分隔符;可以使用flags参数修改此行为。

我遇到了同样的问题，但我cleared问题而不是试图解决它！我尝试在其中显示transparent活动，其中包含布局like菜单，当用户点击菜单时主Activity中的按钮，显示透明活动。我希望这些代码段可以帮助您：

主要活动：

public class MainActivity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ( keyCode == KeyEvent.KEYCODE_MENU ) { 
            Intent i = new Intent(this, MyCustomMenuActivity.class);
            startActivity(i);
        }
        return super.onKeyDown(keyCode, event);
    }

}

CustomMenuActivity：

public class MyCustomMenuActivity extends Activity {
    Button finishButton;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.menu);
        finishButton = (Button) findViewById(R.id.finishbutton);
        finishButton.setOnClickListener(new OnClickListener() { 
            @Override
            public void onClick(View v) {
                MyCustomMenuActivity.this.finish();
            }
        });
    }
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ( keyCode == KeyEvent.KEYCODE_MENU ) {
            finish();
        }
        return super.onKeyDown(keyCode, event);
    }
}

        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:text="Button" />

        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:text="Button" />


    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"

将您的主题更改为AppTheme到AppTheme.NoActionBar。

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> <!-- Customize your theme here. --> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/colorAccent</item> </style> 

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
</style>
