androidmenu自定義
Ⅰ Android 怎麼實現自定義menuItem
可以在xml中自定義item項目為menu
Ⅱ Android如何自定義menu的背景
01.public class MenuEx extends Activity { 02. 03. private static final String TAG = "android123"; 04. @Override 05. public void onCreate(Bundle savedInstanceState) { 06. super.onCreate(savedInstanceState); 07. setContentView(R.layout.main); 08. } 09. @Override 10. public boolean onCreateOptionsMenu(Menu menu) { 11. super.onCreateOptionsMenu(menu); 12. MenuInflater inflater = new MenuInflater(getApplicationContext()); 13. inflater.inflate(R.menu.options_menu, menu); 14. setMenuBackground(); 15. return true; 16. } 01.public class MenuEx extends Activity { 02. 03. private static final String TAG = "android123"; 04. @Override 05. public void onCreate(Bundle savedInstanceState) { 06. super.onCreate(savedInstanceState); 07. setContentView(R.layout.main); 08. } 09. @Override 10. public boolean onCreateOptionsMenu(Menu menu) { 11. super.onCreateOptionsMenu(menu); 12. MenuInflater inflater = new MenuInflater(getApplicationContext()); 13. inflater.inflate(R.menu.options_menu, menu); 14. setMenuBackground(); 15. return true; 16. } 上面的例子可以輕松的替換當前Activity的Menu背景顏色,這里Android開發網再次提醒大家上面加粗的包名不能隨意改動,如果非原生的Android系統,這句可能根據各個廠商編譯的固件來靈活處理。
Ⅲ 安卓編程怎樣自定義menu中的字體大小
一、先到AndroidManifest.xml看看當前的theme是什麼:
比如我這里的是AppTheme
[html] view plain
<application
......
android:theme="@style/MyAppTheme" >
二、然後在資源文件的res/values/styles.xml中找到 你的主題:
[html] view plain
<style name="MyAppTheme" parent="@android:style/Theme.Holo.Light">
三、然後在此添加上一個item,name=android:actionMenuTextAppearance,然後引用你自己定義的文字樣式,不管是大小還是顏色都可以自己定義
[html] view plain
<style name="MyAppTheme" parent="@android:style/Theme.Holo.Light">
<item name="android:actionMenuTextAppearance">@style/MyMenuTextStyle</item>
</style>
<style name="MyMenuTextStyle">
<item name="android:textColor">@android:color/red</item>
<item name="android:textSize">16sp</item>
</style>
Ⅳ 請教一個Android方面在Menu菜單里定義的RadioGroup中返回某個RadioButton的選中狀態的問題
RadioButton在做表單的時候經常用到,在安卓開發中,RadioButton需要和RadioGroup一起使用,表示在一組可選項中,只有一個可以被選中,RadioGroup狀態改變的一個監視器OnCheckedChangeListener,RadioGroup使用的時候調用setOnCheckedChangeListener(),然後重寫OnCheckedChangeListener中的onCheckedChanged()方法,比如:
radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener(){
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// 獲取變更後的選項的ID
int radioButtonId = group.getCheckedRadioButtonId();
switch (radioButtonId) {
case R.id.message_radiobtn:
mFragment = new MessageFragment();
break;
case R.id.contact_radiobtn:
mFragment = new ContactFragment();
break;
case R.id.dynamic_radiobtn:
mFragment = new DynamicFragment();
break;
default:
break;
}
getActivity().getSupportFragmentManager().beginTransaction()
.replace(R.id.realtabcontent, mFragment).commit();
}
});
Ⅳ android menu item的字體樣式和背景顏色怎麼自定義
android旋鈕背景顏色 android按鈕背景顏色 默認情況下,Button使用android系統提供的默認背景。因此在不同平台上或者設備上,button顯示的風格也不相同。android支持修改button默認的顯示風格,可通過Drawable狀態列表替換默認的背景

Ⅶ Android如何自定義Menu
新建自定義Menu————>TabMenu.java如下:
package com.ncw;
import android.content.Context;
import android.graphics.Color;

import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.PopupWindow;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.LinearLayout.LayoutParams;
public class TabMenu extends PopupWindow {
private GridView gridView;
private LinearLayout mLayout;
public TabMenu(Context context, OnItemClickListener bodyClick, int colorBgTabMenu) {
super(context);
mLayout = new LinearLayout(context);
mLayout.setOrientation(LinearLayout.VERTICAL);
gridView = new GridView(context);
gridView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
gridView.setSelector(new ColorDrawable(Color.TRANSPARENT));// 選中的時候為透明色
gridView.setNumColumns(4);
gridView.setStretchMode(GridView.STRETCH_COLUMN_WIDTH);
gridView.setVerticalSpacing(0);
gridView.setHorizontalSpacing(0);
gridView.setPadding(0, 0, 0, 0);
gridView.setGravity(Gravity.CENTER);
gridView.setOnItemClickListener(bodyClick);
mLayout.addView(gridView);
// 設置默認項
this.setContentView(mLayout);
this.setWidth(LayoutParams.FILL_PARENT);
this.setHeight(LayoutParams.WRAP_CONTENT);
this.setBackgroundDrawable(new ColorDrawable(colorBgTabMenu));// 設置TabMenu菜單背景
this.setFocusable(true);// menu菜單獲得焦點 如果沒有獲得焦點menu菜單中的控制項事件無法響應
}
public void SetBodySelect(int index, int colorSelBody) {
int count = gridView.getChildCount();
for (int i = 0; i < count; i++) {
if (i != index)
((LinearLayout) gridView.getChildAt(i))
.setBackgroundColor(Color.TRANSPARENT);
}
((LinearLayout) gridView.getChildAt(index))
.setBackgroundColor(colorSelBody);
}
public void SetBodyAdapter(MenuBodyAdapter bodyAdapter) {
gridView.setAdapter(bodyAdapter);
}
/**
* 自定義Adapter,TabMenu的每個分頁的主體
*
*/
static public class MenuBodyAdapter extends BaseAdapter {
private Context mContext;
private int[] resID;
/**

}
}
@Override
/**

*/
public boolean onCreateOptionsMenu(Menu menu) {
menu.add("menu");// 必須創建一項
return super.onCreateOptionsMenu(menu);

@Override
/**

public boolean onMenuOpened(int featureId, Menu menu) {

Ⅷ android menu怎樣設置item的文字
Android Menu的文字有兩種設置方式:
在 menu.xml中設置。
在java代碼onCreateOptionsMenu中設置。
以下為示例代碼:
在menu.xml中指定title即可
<item android:id="@+id/menu"
android:title="文字"/>重載onCreateOptionsMenu(Menu menu)方法,並調用API。
menu.add((int groupId, int itemId, int order, charsequence title) .setIcon(drawable ID)
add()方法的四個參數,依次是:
1、組別,如果不分組的話就寫Menu.NONE。
2、Id,這個很重要,Android根據這個Id來確定不同的菜單 。
3、順序,哪個菜單項在前面由這個參數的大小決定 。
4、文本,菜單項的顯示文本。
Ⅸ android中menu怎麼寫
菜單資源文件必須放在res/menu目錄中。菜單資源文件必須使用<menu>標簽作為根節點。除了<menu>標簽外,還有另外兩個標簽用於設置菜單項和分組,這兩個標簽是<item>和<group>。
<menu>標簽沒有任何屬性,但可以嵌套在<item>標簽中,表示子菜單的形式。不過<item>標簽中不能再嵌入<item>標簽。
1.<item>標簽的屬性含義如下:
Id:表示菜單項的資源ID
menuCategory:同種菜單項的種類。該屬性可取4個值:container、system、secondary和alternative。通過menuCategroy屬性可以控制菜單項的位置。例如將屬性設為system,表示該菜單項是系統菜單,應放在其他種類菜單項的後面。
orderInCategor:同種類菜單的排列順序。該屬性需要設置一個整數值。例如menuCategory屬性值都為system的3個菜單項(item1、item2和item3)。將這3個菜單項的orderInCategory屬性值設為3、2、1,那麼item3會顯示在最前面,而item1會顯示在最後面。
title:菜單項標題(菜單項顯示的文本)
titleCondensed:菜單項的短標題。當菜單項標題太長時會顯示該屬性值
icon:菜單項圖標資源ID
alphabeticShortcut:菜單項的字母快捷鍵
numericShortcut:菜單項的數字快捷鍵
checkable:表示菜單項是否帶復選框。該屬性可設計為true或false
checked:如果菜單項帶復選框(checkable屬性為true),該屬性表示復選框默認狀態是否被選中。可設置的值為true或false
visible:菜單項默認狀態是否可視
enable:菜單項默認狀態是否被激活
Ⅹ 請問Android中如何自定義Menu菜單,能否給一個示例最好
public class ActivityMenu extends Activity {
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
...
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
....
return super.onOptionsItemSelected(item);
}
}
