我是
Android新手,我正在创建Listview弹出菜单.但我有它的宽度和高度问题.弹出菜单可以采用更高的高度和宽度. SO中有很多问题,但这些都没有帮助我.
private void showPopupMenu(View view){
Context wrapper = new ContextThemeWrapper(this,R.style.PopupMenu);
PopupMenu popupMenu = new PopupMenu(wrapper,view);
popupMenu.getMenuInflater().inflate(R.menu.popup_menu,popupMenu.getMenu());
popupMenu.show();
popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener(){
@Override
public boolean onMenuItemClick(MenuItem item){
switch (item.getItemId()){
case R.id.install:
Intent intent = new Intent(ViewAllRelationActivity.this,EditRelativeActivity.class);
startActivity(intent);
break;
case R.id.addtowishlist:
break;
}
return false;
}
});
}
它给出了这个输出：
我们可以在ContextMenu中保持宽度和高度但是它总是在Center中显示而不是Listview数据的每一行.
但我想要下面的图像类型弹出菜单.宽度和高度都很小.
请为此提供解决方案.
解决方法
如果您使用的是适配器,则可以在适配器中放入getView(…)方法
imvMore.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showPopupMenu(act,v);
}
});
并把方法
private void showPopupMenu(Activity act,View view){
PopupMenu popupMenu = new PopupMenu(act,view);
popupMenu.getMenuInflater().inflate(R.menu.menu_popup,popupMenu.getMenu());
popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
switch (item.getItemId()) {
}
return true;
}
});
popupMenu.show();
}
在您的适配器类中.
注意：act是在创建构造函数适配器时必须绑定的Activity,例如：
public YourAdapter(Activity act,ArrayList<ItemOfYourModel> data){
this.data = data;
this.act = act;
}
在Activity中,您可以编写代码：
ArrayList<ItemOfYourModel> listData = new ArrayList<ItemOfYourModel>(); listData.add(new YourItemOfYourModel(...)); YourAdapter adapter = new YourAdapter(this,listData);
