3. Summary
The usage of floating forms and desktop plug-ins is very important. I will briefly describe them here.
How can I set the priority of an android floating window to hover the self-written floating window over all floating windows and drop-down menus?
If it is set to phone type, it can always be at the top, because the call level is higher than anything else.
This. getWindow (). setType (WindowManager. LayoutParams. TYPE_PHONE );
How do Android widget events and widget button events be defined?
A widget is a non-object package, not a component.
An example is provided in the API documentation.
PublicclassMyActivityextendsActivity {
Protectedvoid onCreate (Bundle icicle ){
Super. onCreate (icicle );
SetContentView (R. layout. content_layout_id );
FinalButton button = (Button) findViewById (R. id. button_id );
Button. setOnClickListener (newView. OnClickListener (){
Publicvoid onClick (View v ){
// Perform action on click
}
});
}
