我想在Android中實現一個像Twitter這樣的自定義彈出式菜單,例如有物品和圖片,但我不知道用於此的組件是什麼。如何使用Material Design Android實現此自定義彈出式菜單?
在Material Design網站上,google存在this solution。所以我認爲,有一個本地解決方案來實現這一點。
我試圖與Popup menu,但我怎麼也找不到自定義此觀點類似的佈局。

您可以使用ListPopupWindow,提交您的自定義適配器,通過它您可以控制ListPopupWindow
的每一行的佈局。至於正常的PopupWindow
,您必須提供錨點視圖,而且您必須在ListPopupWindow
的實例上調用setContentWidth
,該實例將彈出窗口的寬度設置爲其內容的大小。這是一個小的價格,你必須支付,但對於一個小數據集並不是什麼大不了的。我有這個實用方法來檢索行的最大寬度:
public int measureContentWidth(ListAdapter adapter) {
int maxWidth = 0;
int count = adapter.getCount();
final int widthMeasureSpec = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED);
final int heightMeasureSpec = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED);
View itemView = null;
for (int i = 0; i < count; i++) {
itemView = adapter.getView(i, itemView, this);
itemView.measure(widthMeasureSpec, heightMeasureSpec);
maxWidth = Math.max(maxWidth, itemView.getMeasuredWidth());
}
return maxWidth;
}
你將如何獲得該行的材料主題? –
@AnubianNoob我會使用styles.xml – Blackbelt
你會繼承什麼風格?我在爲這兩行和包含它們的ListView而煩惱。 –
有一個名爲PopupMenu
的小部件,它基本上是一個錨定到特定視圖的菜單。一個缺點是它默認不顯示圖標。
但是,您可以使用反射並致電setForceShowIcon
來揭示它們。你需要的代碼是:
由於PopupMenu
被固定在特定的視圖,您ActionBar
項目都有一個actionLayout
屬性。作爲佈局(action_item.xml
)可以很簡單:
<Button
xmlns:android="http://schemas.android.com/apk/res/android"
style="?attr/actionButtonStyle"
android:layout_gravity="center"
android:text="Show popup"
android:textStyle="bold"
android:textSize="12sp"
android:layout_width="wrap_content"
android:layout_height="match_parent"/>
ActionBar
菜單樣式,包含與上述佈局的項目
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/popup_item"
android:title="Show popup"
android:showAsAction="always"
android:actionLayout="@layout/action_item"/>
</menu>
你popup_menu.xml
,你會誇大你的PopupMenu
佈局
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/item1"
android:title="Item1"
android:icon="@mipmap/ic_launcher"/>
</menu>
最後,執行infla的代碼一個ActionBar
項目被點擊
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_add_item:
PopupMenu popup = new PopupMenu(this, item.getActionView());
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.popup_menu, popup.getMenu());
// Use reflection to invoke setForceShowIcon
try {
Field[] fields = popup.getClass().getDeclaredFields();
for (Field field : fields) {
if ("mPopup".equals(field.getName())) {
field.setAccessible(true);
Object menuPopupHelper = field.get(popup);
Class<?> classPopupHelper = Class
.forName(menuPopupHelper.getClass().getName());
Method setForceIcons = classPopupHelper
.getMethod("setForceShowIcon", boolean.class);
setForceIcons.invoke(menuPopupHelper, true);
break;
}
}
} catch (Exception e) {
e.printStackTrace();
}
popup.show();
return true;
}
return super.onOptionsItemSelected(item);
}
注意,當獲得在一個菜單中多行文本離子,你需要使用您的彈出菜單項的actionLayout
了。
使用Pop-Up list fragment。 有關片段的好處是,你可以很容易地animate them 如果你想在彈出的內容完全控制(如果你不明白片段我建議先讀Fragment Introduction)
然後看看Dialog Fragment
這代碼在我的應用程序中工作。
試試這個: -
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".LocationDetailsActivity">
<item xmlns:tools="http://schemas.android.com/tools"
android:icon="@android:drawable/ic_menu_mapmode"
app:showAsAction="ifRoom"
android:title="@string/title_of_menu"
tools:context=".LocationDetailsActivity">
//the menu list with icon
<menu>
<item
android:id="@+id/action_map_type_normal"
android:orderInCategory="100"
android:icon="some_icon" //place your icon here
android:title="Vacation spots" />
<item
android:id="@+id/action_map_type_satellite"
android:orderInCategory="100"
android:icon="some_icon" //place your icon here
android:title="Friends and family" />
<item
android:id="@+id/action_map_type_hybrid"
android:orderInCategory="100"
android:icon="some_icon" //place your icon here
android:title="Restaurants" />
</menu>
</item>

他們都有很好的例子和源代碼,以幫助你
希望這有助於你:)
我已經同issue.but終於讓我找到我自己的解決方案,我正在分享你我碼。希望這會幫助你。
popupWindowDogs = popupWindowDogs(); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub // popupWindowDogs.showAsDropDown(v, -5, 0); popupWindowDogs().showAtLocation(v, Gravity.CENTER, 0, 0); } }); // Detect touched area detector = new SimpleGestureFilter(this, this);
}
public PopupWindow popupWindowDogs() { // initialize a pop up window type PopupWindow popupWindow = new PopupWindow(this); // the drop down list is a list view final ListView listView = new ListView(this); // set our adapter and pass our pop up window contents listView.setAdapter(dogsAdapter(popUpContents)); // listView.setBackgroundColor(Color.DKGRAY); listView.setBackgroundResource(R.drawable.ss4); listView.setPadding(0, 0, 0, 10); listView.setDivider(null); try { listView.setOnScrollListener(new OnScrollListener() { @Override public void onScrollStateChanged(AbsListView view, int scrollState) { View c = listView.getChildAt(0); String cc = listView.getChildAt(0).toString(); int scrolly = -c.getTop() + listView.getFirstVisiblePosition() * c.getHeight(); /* * Toast.makeText(getApplicationContext(), scrolly + "", Toast.LENGTH_SHORT) * .show(); */} @Override public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) { } }); } catch (Exception e) { Toast.makeText(getApplicationContext(), e.toString() + "", Toast.LENGTH_SHORT) .show(); } listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View v, int arg2, long arg3) { try { // TODO Auto-generated method stub Context mContext = v.getContext(); Swipetouch mainActivity = ((Swipetouch) mContext); // add some animation when a list item was clicked Animation fadeInAnimation = AnimationUtils.loadAnimation(v.getContext(), android.R.anim.fade_in); fadeInAnimation.setDuration(10); v.startAnimation(fadeInAnimation); // dismiss the pop up mainActivity.popupWindowDogs.dismiss(); // get the text and set it as the button text String val = (String) arg0.getItemAtPosition(arg2); // Toast.makeText(mContext, val, Toast.LENGTH_SHORT).show(); if (val.equals("Signup Now")) { Intent ii = new Intent(getApplicationContext(), Registration.class); startActivity(ii); stopService(new Intent(Swipetouch.this, MyService.class)); stopService(new Intent(Swipetouch.this, MyService.class)); } else if (val.equals("Login")) { Intent ii = new Intent(getApplicationContext(), MyLoginActivity.class); startActivity(ii); stopService(new Intent(Swipetouch.this, MyService.class)); } else if (val.equals("Exit")) { finish(); stopService(new Intent(Swipetouch.this, MyService.class)); } else if (val.equals("Friends")) { Intent ii = new Intent(getApplicationContext(), MyLoginActivity.class); startActivity(ii); } else if (val.equals("Exit")) { stopService(new Intent(Swipetouch.this, MyService.class)); finish(); } } catch (Exception e) { Toast.makeText(Swipetouch.this, e.toString(), Toast.LENGTH_SHORT).show(); } } }); // some other visual settings popupWindow.setFocusable(true); popupWindow.setWidth(250); // popupWindow.setHeight(300); popupWindow.setHeight(WindowManager.LayoutParams.WRAP_CONTENT); // set the list view as pop up window content // SET WALLPAPER IMAGE /* * popupWindow.setBackgroundDrawable(getWallpaper()); popupWindow.setHeight(300); */ // layout.setBackgroundResource(R.drawable.sshadow); // layout.setBackgroundColor(Color.TRANSPARENT); // popupWindow.setContentView(layout); popupWindow.setBackgroundDrawable(new ColorDrawable( android.graphics.Color.TRANSPARENT)); popupWindow.setContentView(listView); return popupWindow; }
try {
java.lang.reflect.Field[] fields = popup.getClass().getDeclaredFields();
for (java.lang.reflect.Field field : fields) {
if ("mPopup".equals(field.getName())) {
field.setAccessible(true);
Object menuPopupHelper = field.get(popup);
Class<?> classPopupHelper = Class
.forName(menuPopupHelper.getClass().getName());
Method setForceIcons = classPopupHelper
.getMethod("setForceShowIcon", boolean.class);
setForceIcons.invoke(menuPopupHelper, true);
break;
}
}
} catch (Exception e) {
e.printStackTrace();
}
只需在popup.show()之前的這段代碼; 它工作perfectttttllyyyy :) –
容易的解決方案。在.show()方法之前添加。
try {
Field mFieldPopup=popupMenu.getClass().getDeclaredField("mPopup");
mFieldPopup.setAccessible(true);
MenuPopupHelper mPopup = (MenuPopupHelper) mFieldPopup.get(popupMenu);
mPopup.setForceShowIcon(true);
} catch (Exception e) {}
嗨洛佩茲,請試試我的代碼,讓我知道它是否工作與否。謝謝:) – Biswajit
