当ProgressBar在Android中可见时，如何禁用用户交互? [英] How to disable user interaction while ProgressBar is visible in android?

问题描述

我正在使用自定义的ProgressBar.现在，当任务正在进行时，我正在显示进度栏，但是用户仍然可以与视图和控件进行交互. 可见时，如何像ProgressDialog一样在整个视图上禁用用户交互.

I am using a custom ProgressBar. Now while a task is going on, I am showing the progress bar, but user can still interact with the views and controls. How do I disable the user interaction on whole view just like a ProgressDialog does , when it is visible.

我是否需要在主视图上方使用透明视图，并在该视图上显示进度条，并在任务完成后隐藏该视图.

Do I need to use a transparent view on top of main view and show the progress bar on that view and hide that view once a task is completed.

还是只获取我的parentView的ID并将其设置为禁用?但是那样我就无法调暗背景，就像在视图/活动/片段上出现对话框时发生的一样.正确的?

Or just get the id of my parentView and set it disabled ? But then I won't be able to dim the background, just like what happens when a dialog appears on the view/Activity/Fragment. Right?

我只想知道在进度条可见时禁止用户进行任何交互的方法.

I just want to know the way to disallow the user from any interaction while the progressbar is visible.

谢谢

Your question: How to disable the user interaction while ProgressBar is visible in android?

要禁用用户交互，您只需添加以下代码

To disable the user interaction you just need to add the following code

getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,
                    WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);

要恢复用户交互，您只需添加以下代码

To get user interaction back you just need to add the following code

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);

以下是示例: 注意:我仅向您提供一个示例，以说明如何禁用或保留用户互动

在xml中添加进度条.类似的事情

Add a progress bar in your xml.Something like this

<ProgressBar
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/progressBar"
    android:visibility="gone"/>

在MainActivity中，按下按钮时，您将显示进度条并禁用用户交互.

In MainActivity when a button pressed you show the progressbar and disable the user interaction.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mImageView = (ImageView) findViewById(R.id.imageView);
    mProgressBar = (ProgressBar) findViewById(R.id.progressBar);
    mImageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mProgressBar.setVisibility(View.VISIBLE);
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,
                    WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
        }
    });
}

当用户向后按下时，再次删除进度条，保留用户交互.类似的事情

And when user backPressed you remove the progressbar again retain the user interaction.Something like this

  @Override
public void onBackPressed() {
    super.onBackPressed();
    mProgressBar.setVisibility(View.GONE);
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
}

如果要添加禁用和灰显显示功能，则需要在xml布局文件中添加填充父级的线性布局.将其背景设置为#B0000000，并将其visibilty设置为GONE.然后以编程方式将其visibility设置为VISIBLE.

If you want to add a feature of disable and greyed out display, you need to add in your xml layout file a linear layout that fills the parent. Set its background to #B0000000 and its visibilty to GONE. Then programmatically set its visibility to VISIBLE.
