ポップアップウィンドウに問題があります。独自のレイアウトでポップアップ ウィンドウを作成したい。これはコードです：

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);
    }
}

これは、ポップアップウィンドウに設定したいレイアウトです:

<?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>

findbyidこれはActivityではないため、私のクラスではメソッドを使用できません。クラスのポップアップウィンドウに独自のレイアウトを設定するにはどうすればよいですか?

ポップアップを使用する編集アクティビティ:

@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);

}

このコードを試してください：

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) {
           changeSortPopUp.dismiss();
         }
       });

}

次のコードを使用できます。これには PopupWindow を使用する必要があります。 

PopupWindow mpopup;

次に、ビューを膨らませる必要があります。 

    View popUpView = getLayoutInflater().inflate(R.layout.activity_login,
            null); // inflating popup layout
    mpopup = new PopupWindow(popUpView, LayoutParams.FILL_PARENT,
            LayoutParams.WRAP_CONTENT, true); // Creation of popup
    mpopup.setAnimationStyle(android.R.style.Animation_Dialog);
    mpopup.showAtLocation(popUpView, Gravity.CENTER, 0, 0); // Displaying popup

レイアウトにアイテムがある場合は、そのアイテムをビューにバインドする必要があります。 

    TextView some = (TextView) popUpView.findViewById(R.id.some);       
    Button btnCancel = (Button) popUpView.findViewById(R.id.btnCancel);

ポップアップ ウィンドウ アイテムの onClickListener。 

    btnCancel.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            mpopup.dismiss();
        }
    });

を使用して PopupWindow を閉じることができますmpopup.dismiss();

使用できますLayoutInflater

LayoutInflater inflater = (LayoutInflater) act.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.custom_layout, null); //custom_layout is your xml file which contains popuplayout
LinearLayout layout = (LinearLayout) view.findViewById(R.id.popuplayout);

        public void onClick(View v) {
            if (click) {
                popUp.showAtLocation(mainLayout, Gravity.BOTTOM, 10, 10);
                popUp.update(50, 50, 300, 80);
                click = false;

                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);
    // popUp.showAtLocation(layout, Gravity.BOTTOM, 10, 10);
     mainLayout.addView(but, params);
     setContentView(mainLayout);
   }
