圓角圓菜單在安卓

Question

我想創建一個圓圈菜單是這樣的：

我使用ArcMenu庫。 我xml代碼

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:arc="http://schemas.android.com/apk/res-auto" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" > 

<LinearLayout 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical"> 

    <com.capricorn.ArcMenu 
     android:id="@+id/arc_menu" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     /> 
</LinearLayout> 

和MainActivity.java：

public class MainActivity extends Activity { 
private static final int[] ITEM_DRAWABLES = { R.drawable.composer_camera, R.drawable.composer_music, 
     R.drawable.composer_place, R.drawable.composer_sleep, R.drawable.composer_thought, R.drawable.composer_with }; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    ArcMenu menu = (ArcMenu) findViewById(R.id.arc_menu); 

    ArcLayout arcLayout= new ArcLayout(this); 
    arcLayout.setChildSize(50); 
    arcLayout.setArc(0.0f, 300.0f); 



    final int itemCount = ITEM_DRAWABLES.length; 
    for (int i = 0; i < itemCount; i++) { 
     ImageView item = new ImageView(this); 
     item.setImageResource(ITEM_DRAWABLES[i]); 

     final int position = i; 
     menu.addItem(item, new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       Toast.makeText(MainActivity.this, "position:" + position, Toast.LENGTH_SHORT).show(); 
      } 
     });// Add a menu item 
    } 
} 


} 

和輸出不圓的方式到來。

輸出來是這樣：

試用爲

arcLayout.setArc(0.0f, 360.0f); 

編輯：

是沒有用的你的下面的代碼：

ArcLayout arcLayout= new ArcLayout(this); 
    arcLayout.setChildSize(50); 
    arcLayout.setArc(0.0f, 300.0f); 

你只需要改變如下佈局代碼，然後檢查

<com.capricorn.ArcMenu 
     android:id="@+id/arc_menu_2" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     arc:fromDegrees="0.0" 
     arc:toDegrees="360.0" 
     arc:childSize="50dp"/>
