Question

我遇到的问题是我手头没遇到的问题。我想要做的是允许用户使用意图从设备拍摄照片的选项。然后将该照片返回到调用活动，然后显示在图像视图中（现在......）。问题是，昨天一切都在为我和今天工作（......没有用代码改变任何东西......）似乎什么都没做。这似乎是应用程序“悬挂”。不知道如何解决这个问题甚至是解决问题的根本原因。如果有人有任何建议请发布，这里是代码：

//---Pressing this button will allow for user to choose what photo should return---
    Button b2 = (Button) findViewById(R.id.btn_getPhotos);
    b2.setOnClickListener(new OnClickListener()
    {

        public void onClick(View arg0)
        {
            Intent i = new Intent(Intent.ACTION_GET_CONTENT);
            //Intent i = new Intent(Intent.ACTION_PICK);
            i.setType("image/*");

            //**Keep in mind after calling the StartActivityForResult() it seems to hang...**
            startActivityForResult(i, PIC_REQUEST);

        }

    });

这是OnActivityResult（）：

 protected void onActivityResult(int requestCode, int resultCode, Intent data )
{   
    if (resultCode == Activity.RESULT_CANCELED)
    {
       //handles when camera was canceled...
       Toast.makeText(this, "Cancelled by user...", Toast.LENGTH_LONG).show();

    } 

    else if (requestCode == PIC_REQUEST) 
    {   
       Uri photoUri = data.getData();

       try 
       {
            Bitmap galleryPic = Media.getBitmap(getContentResolver(), photoUri);
            ImageView image = (ImageView) findViewById(R.id.currentPhoto); 
            image.setImageBitmap(galleryPic);

        } 
       catch (FileNotFoundException e) 
       {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
       catch (IOException e) 
       {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

最后但并非最不重要的是waring / error log：

11-09 10:07:47.060: WARN/InputManagerService(142): Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@407d13a8

11-09 10:08:06.320: WARN/ActivityManager(142): Activity idle timeout for ActivityRecord{40939988 king.chad.SDE/.MainActivity}

我想说我的问题在于日志的这一部分（基于我研究过的其他论坛相关问题......），但我不确定：

11-09 10:08:23.090: WARN/InputManagerService(142): Starting input on non-focused client com.android.internal.view.IInputMethodClient$Stub$Proxy@407f37e0 (uid=10022 pid=238)

Answer 1

好吧，不知道为什么上面的代码不起作用，但我确实找到了解决这个问题的方法。经过大量阅读和搜索后，我发现这个问题实际上可能与我的代码无关，而是我正在使用的设备。我最后通过更改：

来更改startActivityForResult（）方法

startActivityForResult(i, PIC_REQUEST);

......对此：

startActivityForResult(Intent.createChooser(i, "Select a photo"), PIC_REQUEST);

......现在一切都很好。希望这可以帮助任何可能遇到同样问题的人。
