以编程方式安装android中的应用程序后，如何检测用户是否单击完成或打开 [英] how to detect if user clicked done or open after application in android has been installed programmatically

问题描述

我无法检测用户是否单击了对话框，该对话框通常在安装 android 应用程序后弹出.这样我就可以继续进行下一个安装或活动.

I'm having trouble detecting if the user clicked the dialog, that usually pops up after the android application has been installed. So that I can proceed to the next installation or activity.

推荐答案

如果我没听错，

• 您正在尝试以编程方式安装 APK
• 您需要获取安装成功后用户按下按钮Open 或Done 的状态.

• You are trying to programatically install a APK
• You need to get the status, whether the user pressed buttons Open or Done, after the successful installation.

这是可以做到的.为此，请像这样启动软件包安装程序.

This can be done. For this, start the package installer like this.

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(
Uri.fromFile(new File("Full path to your APK")),
        "application/vnd.android.package-archive"); // the APK path can be in SDCARD or in your application directory. I am sure you know this path.

// start the package-installer activity and wait for result. The second parameter can be used to identify the source of result in `onActivityResult` method. 
startActivityForResult(intent, 1);

• 现在将启动包安装程序，您的 APK 将安装在设备上.
• 用户按下Open 或Done 按钮.
• 您在onActivityResult回调函数中重新获得程序控制
• Now the package installer will be started and your APK will get installed on device.
• User presses either Open or Done buttons.
• You gets the program control back in onActivityResult callback function

onActivityResult 函数:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // requestCode == 1 means the result for package-installer activity
    if (requestCode == 1) 
    {
        // resultCode == RESULT_CANCELED means user pressed `Done` button
        if (resultCode == RESULT_CANCELED) {
            Toast.makeText(this, "User pressed 'Done' button", Toast.LENGTH_SHORT).show();
        } 
        else if (resultCode == RESULT_OK) {
            // resultCode == RESULT_OK means user pressed `Open` button
            Toast.makeText(this, "User pressed 'Open' button", Toast.LENGTH_SHORT).show();
        }
    }
    super.onActivityResult(requestCode, resultCode, data);
}
