问题描述
我有一个弹出式窗口的一个问题。我想创建弹出窗口,我自己的布局。这是code:
公共类PopupWindowView扩展PopupWindow {
PopupWindow弹出;
布尔点击= TRUE;
的LayoutParams PARAMS;
RelativeLayout的mainLayout;
TextView的电视;
的LinearLayout布局;
ImageView的chooseFlag;
公共无效createPopupWindow(活动行为){
弹出=新PopupWindow(行为);
chooseFlag =(ImageView的)act.findViewById(R.id.login_choose_flag);
mainLayout =(RelativeLayout的)act.findViewById(R.id.login_layout);
电视=新的TextView(行为);
布局=新的LinearLayout(行为);
//布局=(的LinearLayout)findViewById(R.id.popuplayout);
chooseFlag.setOnClickListener(新OnClickListener(){
@覆盖
公共无效的onClick(视图v){
如果(点击进入){
INT []值=新INT [2];
v.getLocationOnScreen(值);
popup.showAtLocation(mainLayout,Gravity.NO_GRAVITY,10,10);
popup.update(值[0],值[1],300,80);
点击= FALSE;
} 其他 {
popup.dismiss();
点击= TRUE;
}
}
});
PARAMS =新的LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
layout.setOrientation(LinearLayout.VERTICAL);
tv.setText(你好,这是一个简单的文本弹出窗口);
layout.addView(电视,则params);
popup.setContentView(布局);
}
}
这是布局,我想在我的弹出式窗口设置:
< XML版本=1.0编码=UTF-8&GT?;
< LinearLayout中的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:layout_width =match_parent
机器人:layout_height =match_parent
>
<的LinearLayout
机器人:ID =@ + ID / popuplayout
机器人:layout_width =match_parent
机器人:layout_height =match_parent
机器人:背景=@色/ patient_button_bg>
< / LinearLayout中>
< / LinearLayout中>
在我的课,我不能使用 findbyid
的方法,因为这不是活动。我如何设置,在弹出的遗孀我自己的布局在我的课?

编辑活动其中使用弹出窗口:
@覆盖
保护无效的onCreate(包savedInstanceState){
super.onCreate(savedInstanceState);
的setContentView(R.layout.activity_login);
getActionBar()隐藏()。
mainMenuGenerator =新MainMenuGenerator();
mainMenuGenerator.generateMainMenu(本);
mainMenuGenerator.hideIcons();
弹出=新PopupWindowView();
popup.createPopupWindow(本);
}
解决方案
试试这个code:
私人无效showSortPopup(最后的活动范围内,点P)
{
//膨胀popup_layout.xml
LinearLayout中的ViewGroup =(的LinearLayout)context.findViewById(R.id.llSortChangePopup);
LayoutInflater layoutInflater =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
查看布局= layoutInflater.inflate(R.layout.sort_popup_layout,ViewGroup中);
//创建PopupWindow
changeSortPopUp =新PopupWindow(上下文);
changeSortPopUp.setContentView(布局);
changeSortPopUp.setWidth(LinearLayout.LayoutParams.WRAP_CONTENT);
changeSortPopUp.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT);
changeSortPopUp.setFocusable(真正的);
//有些偏移对准弹出有点向左,有点下降,相对于按钮的位置。
INT OFFSET_X = -20;
INT OFFSET_Y = 95;
//清除默认的半透明背景
changeSortPopUp.setBackgroundDrawable(新BitmapDrawable());
//显示弹出指定位置,+偏移。
changeSortPopUp.showAtLocation(布局,Gravity.NO_GRAVITY,PX + OFFSET_X,PY + OFFSET_Y);
//获取一个参考关闭按钮,点击后关闭弹出窗口。
按钮,关闭=(按钮)layout.findViewById(R.id.close);
close.setOnClickListener(新OnClickListener(){
@覆盖
公共无效的onClick(视图v){
popup.dismiss();
}
});
}
I have a problem with popup window. I want to create popup window with my own layout.This is code:
public class PopupWindowView extends PopupWindow{
PopupWindow popup;
boolean click = true;
LayoutParams params;
RelativeLayout mainLayout;
TextView tv;
LinearLayout layout;
ImageView chooseFlag;
public void createPopupWindow(Activity act){
popup = new PopupWindow(act);
chooseFlag = (ImageView) act.findViewById(R.id.login_choose_flag);
mainLayout = (RelativeLayout) act.findViewById(R.id.login_layout);
tv = new TextView(act);
layout = new LinearLayout(act);
//layout = (LinearLayout) findViewById(R.id.popuplayout);
chooseFlag.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (click) {
int[] values = new int[2];
v.getLocationOnScreen(values);
popup.showAtLocation(mainLayout, Gravity.NO_GRAVITY, 10, 10);
popup.update(values[0], values[1], 300, 80);
click = false;
} else {
popup.dismiss();
click = true;
}
}
});
params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
layout.setOrientation(LinearLayout.VERTICAL);
tv.setText("Hi this is a sample text for popup window");
layout.addView(tv, params);
popup.setContentView(layout);
}
}
and this is layout which I want to set in my popup window:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout
android:id="@+id/popuplayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/patient_button_bg">
</LinearLayout>
</LinearLayout>
In my class I can't use findbyid
method because this is not Activity. How I can set my own layout in popup widow in my class?

EditActivity which use popup:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
getActionBar().hide();
mainMenuGenerator = new MainMenuGenerator();
mainMenuGenerator.generateMainMenu(this);
mainMenuGenerator.hideIcons();
popup = new PopupWindowView();
popup.createPopupWindow(this);
}
解决方案
try this code:
private void showSortPopup(final Activity context, Point p)
{
// Inflate the popup_layout.xml
LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.llSortChangePopup);
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = layoutInflater.inflate(R.layout.sort_popup_layout, viewGroup);
// Creating the PopupWindow
changeSortPopUp = new PopupWindow(context);
changeSortPopUp.setContentView(layout);
changeSortPopUp.setWidth(LinearLayout.LayoutParams.WRAP_CONTENT);
changeSortPopUp.setHeight(LinearLayout.LayoutParams.WRAP_CONTENT);
changeSortPopUp.setFocusable(true);
// Some offset to align the popup a bit to the left, and a bit down, relative to button's position.
int OFFSET_X = -20;
int OFFSET_Y = 95;
// Clear the default translucent background
changeSortPopUp.setBackgroundDrawable(new BitmapDrawable());
// Displaying the popup at the specified location, + offsets.
changeSortPopUp.showAtLocation(layout, Gravity.NO_GRAVITY, p.x + OFFSET_X, p.y + OFFSET_Y);
// Getting a reference to Close button, and close the popup when clicked.
Button close = (Button) layout.findViewById(R.id.close);
close.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
popup.dismiss();
}
});
}
