我的相机意图有点问题。据我所知，当相机方向改变时，活动会重新启动。Okej，我正在使用下面的代码。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
app = (myApplication)getApplication();
if(savedInstanceState ==null ) getFullImage(null);
else{
String somevalue = savedInstanceState.getString("uri");
getFullImage(somevalue);
}
}
private void getFullImage(String testValue)
{ if(testValue == null){
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
file = new File(Environment.getExternalStorageDirectory(), UUID.randomUUID()+ ".jpg");
outputFile = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFile);
startActivityForResult(intent, TAKE_PICTURE);
}else
{
outputFile = null;
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
file = new File(testValue);
outputFile = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, testValue);
startActivityForResult(intent, TAKE_PICTURE);
finishFromChild(getParent());
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == RESULT_CANCELED) {
Log.i(TAG, "Back Button");
finishFromChild(this);
}
else
if(requestCode == TAKE_PICTURE && resultCode == RESULT_OK)
{
//I'm creating new file here (for this question is irelevant)
} catch (IOException e) {
e.printStackTrace();
}
Intent myIntent = new Intent(getBaseContext(), com.test.activities.SaveFileActivity.class);
myIntent.putExtra("image", newPath);
startActivityFromChild(this, myIntent, SAVE_ITEM);
finishFromChild(this);
}
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putString("uri",outputFile.getPath());
}
捕获图片后，我按 DONE 按钮并转到 SaveFileActivity。Everyting 工作正常，直到我尝试从 SaveFIleActivity 转到另一个活动，然后相机再次启动。我应该在哪里寻找问题？也许我应该杀死相机意图，但是什么时候？
