我正在通过 Eclipse 开发一个 Android 应用程序，我在查找导致以下错误的原因时遇到了一些问题:
我正在调用一个 ACTION_IMAGE_CAPTURE Intent 来打开相机，并期望在结果上显示图像。所以:
Intent v_Intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
try
{
v_Intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(createImageFile()));
}
catch (IOException e)
{
Builder v_Builder = new AlertDialog.Builder(GroupPageActivity.this);
v_Builder.setIcon(android.R.drawable.ic_dialog_alert);
v_Builder.setTitle("Arquivo não Anexado");
v_Builder.setMessage(R.string.cameraSaveErrorInfo).setNegativeButton("OK", null).show();
e.printStackTrace();
return;
}
v_Intent.putExtra("return-data", true);
GroupPageActivity.this.startActivityForResult(v_Intent, IMAGE_CAMERA_REQUEST_ATTACHMENT_CODE);
在这里期待它:
protected void onActivityResult(int p_Code, int p_Result, Intent p_Intent)
{
if (p_Result != RESULT_CANCELED)
{
switch (p_Code)
{
...
case IMAGE_CAMERA_REQUEST_ATTACHMENT_CODE:
{
if (p_Intent != null)
{
Uri capturedImageUri = p_Intent.getData();
//capturedImageUri = g_ImageUri;
if (capturedImageUri != null)
{
m_ImageUriList.add(capturedImageUri);
new CallAddThumbnails().execute();
}
else {
Builder v_Builder = new AlertDialog.Builder(GroupPageActivity.this);
v_Builder.setIcon(android.R.drawable.ic_dialog_alert);
v_Builder.setTitle("Arquivo não Anexado");
v_Builder.setMessage(R.string.cameraImageErrorInfo).setNegativeButton("OK", null).show();
}
}
else
{
Uri capturedImageUri = Uri.parse(g_CurrentPhotoPath);
m_ImageUriList.add(capturedImageUri);
new CallAddThumbnails().execute();
}
break;
}
}
}
}
我能够启动相机 Activity ，拍摄照片，但是，有时，并非总是，我得到这个:
Activity MyApp.GroupPageActivity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@40583060 that was originally added here

调用在此 GroupPageActivity 上。而且我确信，当它发生时，它会在调用 onActivityResult 之前崩溃。
有什么想法吗？
PS.: 我在这里抛出另一个异常:
Private Phone m_UserPhone = ConfigurationController.GetActiveNotNull();
这是 GroupPageActivity 的成员。
PS2.:我注意到，当我拍照时，从 Eclipse 到我正在调试的设备的调试连接在相机 Activity 中终止了。当我确认拍摄的照片时，它崩溃了。
最佳答案
去掉这一行再试一次...
v_Intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(createImageFile()));
发生这种情况是因为 uri 泄漏异常...最好不要将 uri 传递给获取文件的 Intent
关于java - android.view.WindowLeaked 后 Camera Intent，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28501971/
