- 新建一個(gè) GlancePictureFragment，繼承自 DialogFragment
public class GlancePictureFragment extends DialogFragment {
private static final String ARG_PATH = "path";
private ImageView mImage;
public static GlancePictureFragment newInstance(String path) {
Bundle args = new Bundle();
args.putString(ARG_PATH, path);
GlancePictureFragment fragment = new GlancePictureFragment();
fragment.setArguments(args);
return fragment;
}
@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
String path = getArguments().getString(ARG_PATH);
final Dialog dialog = new Dialog(getActivity(), R.style.CustomDialogTheme);
dialog.setContentView(R.layout.dialog_image_glance);
mImage = (ImageView) dialog.findViewById(R.id.glance_image);
mImage.setImageBitmap(
PictureUtils.getScaledBitmap(path, getActivity()));
mImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
return dialog;
}
}
- 在圖片的點(diǎn)擊事件中聲明
mPhotoView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
FragmentManager manager = getFragmentManager();
GlancePictureFragment dialog = GlancePictureFragment
.newInstance(mPhotoFile.getPath());
dialog.show(manager, DIALOG_GLANCE_PICTURE);
}
});
- 添加dialog_image_glance.xml布局文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/glance_image"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
- 在style.xml中添加自定義的主題
略縮圖
點(diǎn)擊略縮圖后查看陋習(xí)現(xiàn)場(chǎng)細(xì)節(jié)
