Question

我尝试创建一个弹出窗口，其中包含多个RelativeLayout，多个TextView和一个Button。

这是弹出窗口：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/popup_handphone_MainLayout"
    android:layout_width="match_parent" android:layout_height="match_parent">

    <RelativeLayout
        android:id="@+id/popup_handphone_Wrapper"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <TextView
            android:id="@+id/popup_handphone_text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/popupPhoneMessage"/>

        <RelativeLayout
            android:id="@+id/popup_handphone_functionalities"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/popup_handphone_text"
            android:layout_marginTop="15dp">

            <EditText
                android:id="@+id/popup_handphone_phoneNumber"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" />

            <EditText
                android:id="@+id/popup_handphone_phoneNumberConfirm"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_below="@+id/popup_handphone_phoneNumber"
                android:layout_marginTop="10dp"/>

            <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_below="@+id/popup_handphone_phoneNumberConfirm"
                android:layout_marginTop="20dp"
                android:layout_marginBottom="40dp"/>

        </RelativeLayout>

    </RelativeLayout>

</RelativeLayout>

如何在Activity上显示它？尝试使用LayoutInflater，但收到错误，说它找到View而不是..

代码：

RelativeLayout mainLayout = (RelativeLayout)findViewById(R.id.popup_handphone_MainLayout);

        LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        RelativeLayout popupLayoutInflater = inflater.inflate(R.layout.popup_handphone, mainLayout);

//This part here said it needs android.widget.RelativeLayout, but found android.view.View

        popupLayout = (RelativeLayout)findViewById(R.layout.popup_handphone);

这是我想要的弹出窗口。灰色的弹出窗口包含两个TextViews和一个Button

使用此tutorial管理创建弹出窗口。但弹出窗口周围有黑色背景，如此

这是onclick

上TextView的更新代码

View.OnClickListener phoneReinputHandler = new View.OnClickListener() {

        public void onClick(View v) {
            Intent intent = new Intent(SignupStepTwoActivity.this, PopupHandphone.class);
            backDim = (RelativeLayout) findViewById(R.id.bac_dim_layout);
            //backDim.setVisibility(View.VISIBLE);
            startActivity(intent);

    };

如何删除黑色东西？

看到这个并根据您的需要进行修改

public void showDialog()
{
    final Dialog dialog = new Dialog(mContext, android.R.style.ThemeOverlay_Material);/*choose your theme*/
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));/*choose your style*/
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);/*to remove title*/
         dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT); //Optional
    dialog.setContentView(R.layout.dialog_dash_wish);/*enter your xml layout name*/
    //Any other code you want in your constructor

    TextView popup_handphone_text = (TextView) dialog.findViewById(R.id.popup_handphone_text);
    EditText popup_handphone_phoneNumber = (EditText) dialog.findViewById(R.id.popup_handphone_phoneNumber);

    EditText popup_handphone_phoneNumberConfirm = (EditText) dialog.findViewById(R.id.popup_handphone_phoneNumberConfirm);

    Button button = (Button) dialog.findViewById(R.id.bt_id);
    button .setOnClickListener(new OnClickListener()
    {
        @Override
        public void onClick(View arg0)
        {
            dialog.dismiss();
        }
    });
    dialog.show();
}
