Question

我想创建一个具有Main类和CustomPopup类的Android应用程序。

在主要活动中，用户可以在文本字段中输入消息，当按下“GENERATE POPUP”按钮时，消息将在屏幕上显示为弹出窗口。弹出窗口必须是可移动的（在屏幕上拖动）。

到目前为止我做了什么，我真的需要帮助代码。

自定义弹出类

public class CustomPopup extends PopupWindow {

private String message;
private Double anchorX;
private Double anchorY;

PopupWindow popup;


public CustomPopup(String message) {
super();
this.message = message;

}

public void showPopup(Activity context)
{
LayoutInflater inflater = (LayoutInflater)context.getSystemService
  ( Context.LAYOUT_INFLATER_SERVICE);
}
}

主要类

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

EditText messageTxt = (EditText) findViewById(R.id.messageTxt);
Button generateBtn = (Button) findViewById(R.id.generateBtn);

String message = messageTxt.getText().toString();

 final CustomPopup popup = new CustomPopup(message);

generateBtn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        popup.showPopup();



    }
});


}
}

我正在使用 PopupHelper 类，您可以使用此代码：

public class PopUpHelper {

    static Dialog dialog;

    public static void showDialog(Activity activity, PINConfirmButtonClickListener action) {
        if (dialog != null && dialog.isShowing()) {
            boolean isShowing = dialog.isShowing();
            return;
        }
        dialog = new Dialog(activity, R.style.MyAlertDialogStyle);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.(your_dialog_layout);
        dialog.setCanceledOnTouchOutside(true);
        dialog.setCancelable(true);
        dialog.show();
          dialog.findViewById(R.id.cancel_button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
         action.onPositiveClicked()
              "YOUR_ACTION_HERE"
            }
        });
        dialog.findViewById(R.id.cancel_button).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
 action.onNegative()
              "YOUR_ACTION_HERE"
            }
        });
        dialog.findViewById(R.id.close_dialog_rl).setOnClickListener(view -> action.onCloseButtonClicked(dialog));
        dialog.findViewById(R.id.resend_code_tv).setOnClickListener(view -> action.onResendCodeClicked());
    }
       public interface TwoButtonClickListener {
        void onPositiveClicked(Dialog dialog);

        void onNegativeClicked(Dialog dialog);
    }

}

MyDialogStyle：（添加到styles.xml）

<!-- Alert Dialog Style-->
    <style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <!-- Used for the border radius -->
        <item name="android:bottomLeftRadius">5dp</item>
        <item name="android:bottomRightRadius">5dp</item>
        <item name="android:topRightRadius">5dp</item>
        <item name="android:topLeftRadius">5dp</item>
        <item name="android:autofilledHighlight" tools:targetApi="o">@color/transparent</item>
    </style>

并在调用 Popup 的活动中：

PopUpHelper.showDialog(this, new PopUpHelper.TwoButtonClickListener() {
            @Override
            public void onPositiveClicked(Dialog dialog) {
                dialog.dismiss();
            
                startHomeActivity();
            }

            @Override
            public void onNegativeClicked(Dialog dialog) {
                dialog.dismiss();
            }

         
        });

如果背景透明不起作用将“android:background="@android:color/transparent”设置为对话框布局

以我的布局为例，但您可以删除字体和某些字段：
