好的我想要实现的是ET-Money安卓应用程序中的以下行为: 在点击2016年12月的微调器时,会有一个视图向下滑动屏幕并使背景视图/布局可见性变暗。
到目前为止我所做的是创建了一个片段(透明的深色背景),它与当前的活动布局重叠,并在点击时添加了幻灯片转换。
但这不是我需要的确切行为,因为这样片段SLIDES的整个黑暗透明布局在当前活动中,我需要的是背景布局淡入黑色而不是与片段布局一起滑入。 (与原始应用程序中一样,只是白色背景中的日期选择视图在活动中滑动,背景同时消失)
我如何实现所需的行为?
MainActivity:
public class MainActivity extends AppCompatActivity {
public Button clickme;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final android.app.Fragment fragment = this.getFragmentManager().findFragmentById(R.id.menuFragment);
this.getFragmentManager().beginTransaction().hide(fragment).commit();
clickme = (Button) findViewById(R.id.clickme);
clickme.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "clicked", Toast.LENGTH_SHORT).show();
FragmentManager fragmentManager = getFragmentManager();
android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.setCustomAnimations(R.animator.slide_up, 0);
fragmentTransaction.show(fragment).commit();
}
});
}
}

感谢 fisher3421 的唯一评论,最后通过 DialogFragment 获得了所需的行为。
以下是工作代码:
MainActivity:
public class MainActivity extends AppCompatActivity {
public Button clickme;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
clickme = (Button) findViewById(R.id.clickme);
clickme.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "clicked", Toast.LENGTH_SHORT).show();
FragmentManager fm = getSupportFragmentManager();
// FragmentTransaction ft = fm.beginTransaction();
MyFrag dFragment = new MyFrag();
// Show DialogFragment
dFragment.show(fm, "Dialog Fragment");
}
});
}
}
MyFrag.java(DialogFragment)
public class MyFrag extends DialogFragment {
Button button ;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.firstfrag, container,
false);
getDialog().setTitle("DialogFragment Tutorial");
// getDialog().setCanceledOnTouchOutside(true);
// Do something else
return rootView;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
final Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.getWindow().getAttributes().windowAnimations = R.style.detailDialogAnimation;
return dialog;
}
@Override
public void onStart()
{
super.onStart();
// safety check
if (getDialog() == null)
return;
int dialogWidth = 700; // specify a value here
int dialogHeight = 600 ; // specify a value here
getDialog().getWindow().setLayout(dialogWidth, dialogHeight);
// ... other stuff you want to do in your onStart() method
}
}
