我尝试开发的应用程序有一点问题。这只是一个小相机应用程序。
这就是我想要做的：...拍照并保存。开始另一个活动，在图片视图中加载图片（因此我保存图片路径，因此我可以使用 BitmapFactory.decodeFile(picutrepath) 加载/创建 bmp）...
但这不起作用。屏幕变黑，甚至没有加载 xml。我总是收到一个 System.out 说“不是正常打开的 drm 文件”，但我不知道这是否与我尝试通过 BitmapFactory 加载图片有关。我使用 Log.i 查看我使用的路径是否有问题，但一切都很好。所以我决定尝试是否可以从我的 R.drawables 加载一个简单的 .png 图像，但这也不起作用。奇怪的是，在屏幕变黑后，应用程序只是退出/退出而没有错误。
希望有人可以帮助我，谢谢:)
这是代码：
我如何开始我的第二个活动：
.
.
.
takepictureButton = (ImageButton) findViewById(R.id.cameralayout_takepictureButton);
takepictureButton.setOnClickListener(new ImageButton.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
camera.takePicture(shutterCallback, rawCallback, jpgCallback);
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.i("", "Starting INTENT");
intentstart();
}
});
.
.
.
private void intentstart() {
// TODO Auto-generated method stub
Intent intent = new Intent(this, FacebarActivity.class);
startActivity(intent);
}
.
.
.
我想开始的活动：
public class FacebarActivity extends Activity {
private ImageView imageview;
private ImageButton cButton, xButton;
private Bitmap picture;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pictureview);
ImageView imageview = (ImageView) findViewById(R.id.pictureviewLayout_pictureView);
picture = BitmapFactory.decodeResource(getResources(),
R.drawable.buttonplay);
imageview.setImageBitmap(picture);
cButton = (ImageButton) findViewById(R.id.pictureviewLayout_CButton);
cButton.setOnClickListener(new ImageButton.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
}
});
XButton = (ImageButton) findViewById(R.id.pictureviewLayout_XButton);
XButton.setOnClickListener(new ImageButton.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
}
});
startthis();
}
还有我用 setContentView() 加载的 pictureview.xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
tools:context=".CameraActivity" >
<RelativeLayout
android:id="@+id/pictureviewLayout_topbarlinearlayout"
android:layout_width="fill_parent"
android:layout_height="75dp"
android:layout_alignParentTop="true"
android:background="@drawable/topbar" >
</RelativeLayout>
<ImageView
android:id="@+id/pictureviewLayout_pictureView"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_above="@+id/pictureviewLayout_bottombarlinearlayout"
android:layout_below="@+id/pictureviewLayout_topbarlinearlayout" />
<RelativeLayout
android:id="@+id/pictureviewLayout_bottombarlinearlayout"
android:layout_width="fill_parent"
android:layout_height="75dp"
android:layout_alignParentBottom="true"
android:background="@drawable/bottombar" >
<ImageButton
android:id="@+id/pictureviewLayout_CButton"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_alignTop="@+id/pictureviewLayout_XButton"
android:layout_centerHorizontal="true"
android:background="@android:color/transparent"
android:src="@android:drawable/ic_menu_camera" />
<ImageButton
android:id="@+id/pictureviewLayout_XButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginRight="24dp"
android:layout_toLeftOf="@+id/pictureviewLayout_CButton"
android:background="@android:color/transparent"
android:src="@android:drawable/ic_notification_clear_all" />
</RelativeLayout>
