推荐答案
您可以在任何单击的视图上使用 PopupMenu
.
You can use PopupMenu
on any view clicked.
完整演示:
MainActivity:
package pk.sohail.gallerytest.activity;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.PopupMenu;
import android.widget.Toast;
import java.lang.reflect.Field;
import pk.sohail.gallerytest.R;
public class MainActivity extends Activity {
Context context;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context = this;
Button btn = (Button) findViewById(R.id.button);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
PopupMenu popupMenu = new PopupMenu(context, view);
popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {
case R.id.one:
Toast.makeText(getApplicationContext(), "1",
Toast.LENGTH_SHORT).show();
return true;
case R.id.two:
Toast.makeText(getApplicationContext(), "2",
Toast.LENGTH_SHORT).show();
return true;
case R.id.three:
Toast.makeText(getApplicationContext(), "3",
Toast.LENGTH_SHORT).show();
return true;
}
return false;
}
});
popupMenu.inflate(R.menu.main);
// Force icons to show
Object menuHelper;
Class[] argTypes;
try {
Field fMenuHelper = PopupMenu.class.getDeclaredField("mPopup");
fMenuHelper.setAccessible(true);
menuHelper = fMenuHelper.get(popupMenu);
argTypes = new Class[]{boolean.class};
menuHelper.getClass()
.getDeclaredMethod("setForceShowIcon", argTypes)
.invoke(menuHelper, true);
} catch (Exception e) {
// Possible exceptions are NoSuchMethodError and
// NoSuchFieldError
//
// In either case, an exception indicates something is wrong
// with the reflection code, or the
// structure of the PopupMenu class or its dependencies has
// changed.
//
// These exceptions should never happen since we're shipping the
// AppCompat library in our own apk,
// but in the case that they do, we simply can't force icons to
// display, so log the error and
// show the menu normally.
Log.w("as", "error forcing menu icons to show", e);
popupMenu.show();
return;
}
popupMenu.show();
}
});
}
}
activity_main.xml:
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Pop Menu"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
R.menu.main:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.example.admin.sst.Signuplogin">
<item
android:id="@+id/one"
android:icon="@mipmap/ic_launcher"
android:title="one"
app:showAsAction="never" />
<item
android:id="@+id/two"
android:icon="@mipmap/ic_launcher"
android:orderInCategory="100"
android:title="two"
app:showAsAction="never" />
<item
android:id="@+id/three"
android:icon="@mipmap/ic_launcher"
android:orderInCategory="100"
android:title="three"
app:showAsAction="never" />
</menu>
