我有一个按钮:
<Button
android:id="@+id/bot_button1"
android:layout_width="120dp"
android:layout_height="fill_parent"
android:layout_weight="1"
android:textSize="24sp"
android:text="@string/bot_button1_tx" />
这是我的主要活动:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
activity = this;
setContentView(R.layout.activity_main);
button1 = (Button) findViewById(R.id.bot_button1);
button1.setOnClickListener(onClickListener);
Log.d(className, "onCreate");
private OnClickListener onClickListener = new OnClickListener() {
@Override
public void onClick(final View v) {
switch(v.getId()){
case R.id.bot_button1:
showPopupMenu(v, 1);
break;
}
}
};
private void showPopupMenu(final View v, Integer i){
PopupMenu popupMenu = new PopupMenu(MainActivity.this, v);
switch (i) {
case 1:
popupMenu.getMenuInflater().inflate(R.menu.menu1, popupMenu.getMenu());
break;
}
popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
new AlertDialog.Builder(activity).
setTitle("TITLE").
setMessage("MESSAGE").
setAdapter(adapter, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO: user specific action
dialog.dismiss();
}
}).create().show();
return true;
}
});
popupMenu.show();
}
选择(单击)弹出菜单中的项目时,如何显示更多项目?理想情况:弹出菜单在选择后保持可见,新的弹出菜单出现在所选项目的右侧。或弹出菜单展开以显示子项。
我试图在menuitemclick()上引入第二个弹出菜单,但它只替换了第一个弹出菜单。
最佳答案
我用了一个新的弹出菜单来解决这个问题
public OnMenuItemClickListener listener = new OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu2_3_3:
popupMenu2.getMenuInflater().inflate(R.menu.menu2_3_3, popupMenu2.getMenu());
popupMenu2.show();
popupMenu2.setOnMenuItemClickListener(listener2);
