Question

我正在使用警报框，这不适合我的设备屏幕。特别是宽度，我可以通过添加空视图来增加高度，但我无法增加宽度。它在左侧和右侧总是有一些空的空间。

我不确切知道它是android的默认属性还是重新调整大小。我也尝试过自定义提示框，但它对我不起作用。此警报框将更新进度并显示，直到完成进度。

这是我的代码：

 LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View view = inflater.inflate(R.layout.sync_dialog, null);

        AlertDialog.Builder alertBuilder = new AlertDialog.Builder(activity);

        alertBuilder.setView(view);

        alertBuilder.setCancelable(false);

        AlertDialog progress = alertBuilder.create();

        // Dialogs set their Window's top level layout width and height to WRAP_CONTENT. 
        // To make the Dialog bigger, you can set those parameters to FILL_PARENT.

        progress.setCanceledOnTouchOutside(false);

        progress.setCancelable(false);

        progress.getWindow().getAttributes().width = LayoutParams.MATCH_PARENT;
        progress.getWindow().getAttributes().height = LayoutParams.MATCH_PARENT;

        mProgress = (ProgressBar) view.findViewById(R.id.progress);


        /*Dialog dialog = new Dialog(activity, android.R.style.Theme_Translucent_NoTitleBar);

        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.sync_dialog);
        dialog.setCanceledOnTouchOutside(false);


        mProgress = (ProgressBar) view.findViewById(R.id.progress);*/

        mText = (TextView) view.findViewById(R.id.message);

        //Rebuilds ProgressBar with saved state when closed

        if (!firstTime) {

                mText.setText(mCurrentStatus);

                mProgress.setProgress(mProgressStatus);

        }

        mProgress.setMax(mProgressMax);         



        return progress;

布局文件是：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >



<LinearLayout
    android:id="@+id/body"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:baselineAligned="false"
    android:orientation="vertical"
    android:paddingBottom="10dip"
    android:paddingLeft="8dip"
    android:paddingRight="8dip"
    android:paddingTop="10dip" >


     <ImageView
        android:id = "@+id/btn_mfa_home"
        android:src="@drawable/ic_mfa_icon_home"
        android:layout_width="match_parent"
        android:layout_height="fill_parent"         
        /> 



    <ImageView
        android:id = "@+id/btn_sync_home"
        android:src="@drawable/btn_sync_home"
        android:paddingTop="50dp"
        android:layout_width="match_parent"
        android:layout_height="fill_parent"         
        /> 


    <TextView
        android:id="@+id/message"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginBottom="12dip"
        android:text="@string/dialog_initial_syncing"
        android:textColor="@android:color/black" />




    <ProgressBar
        android:id="@+id/progress"
        style="@android:style/Widget.ProgressBar.Horizontal"
        android:layout_gravity="center_horizontal"
        android:layout_width="240dip"
        android:layout_height="wrap_content"
        android:max="100" />

</LinearLayout>

任何建议都将不胜感激！

Answer 1

你不是setting the attrbutes on the dialog

这样的事情可能会有所帮助

 AlertDialog.Builder adb = new AlertDialog.Builder(this);
    Dialog d = adb.setView(new View(this)).create();
    // (That new View is just there to have something inside the dialog that can grow big enough to cover the whole screen.)

    WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
    lp.copyFrom(d.getWindow().getAttributes());
    lp.width = WindowManager.LayoutParams.MATCH_PARENT;
    lp.height = WindowManager.LayoutParams.MATCH_PARENT;
    d.show();
    d.getWindow().setAttributes(lp);

请注意，在显示对话框后设置属性。系统在设置时很挑剔。

Answer 2

尝试使用LayoutParams

mDialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.MATCH_PARENT);

Answer 3

我帮助您，请在yourAlertDialog.show（）

之后单独使用它

alertDialog.show(); alertDialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

Alert Box不适合android中的屏幕
