Question

我所拥有的是弹出菜单，其中存在两个活动。一个用于编辑，第二个用于删除。发生的事情就是当我点击编辑时没有任何反应，但是当我点击删除时它会带我去编辑活动。我在logcat中什么也没得到。

token.xml：

 <menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
    android:id="@+id/action_edit"
    android:icon="@drawable/ic_action_edit"
    android:title="@string/edit"/>
<item
    android:id="@+id/action_delete"
    android:icon="@android:drawable/ic_menu_delete"
    android:title="@string/delete" />
</menu>

TokenAdapter.java

     protected void bindView(View view, final int position) {
    final Context ctx = view.getContext();
    TokenLayout tl = (TokenLayout) view;
    Token token = getItem(position);

    tl.bind(token, org.fedorahosted.freeotp.R.menu.token, new PopupMenu.OnMenuItemClickListener() {
        @Override
        public boolean onMenuItemClick(MenuItem item) {
            Intent i;

            switch (item.getItemId()) {
                case org.fedorahosted.freeotp.R.id.action_edit:

                    i = new Intent(ctx, EditActivity.class);
                    i.putExtra(EditActivity.EXTRA_POSITION, position);
                    ctx.startActivity(i);
                    return true;


                case org.fedorahosted.freeotp.R.id.action_delete:

                    Intent i2 = new Intent(ctx, DeleteActivity.class);
                    i2.putExtra(DeleteActivity.EXTRA_POSITION, position);
                    ctx.startActivity(i2);
                    return true;

                default:
                    return false;

            }


        }
    });

    tl.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            TokenPersistence tp = new TokenPersistence(ctx);

            // Increment the token.
            Token token = tp.get(position);
            TokenCode codes = token.generateCodes();
            tp.save(token);

            // Copy code to clipboard.
            mClipMan.setPrimaryClip(ClipData.newPlainText(null, codes.getCurrentCode()));
            Toast.makeText(v.getContext().getApplicationContext(),
                    org.fedorahosted.freeotp.R.string.code_copied,
                    Toast.LENGTH_SHORT).show();

            mTokenCodes.put(token.getID(), codes);
            ((TokenLayout) v).start(token.getType(), codes, true);
        }
    });

    TokenCode tc = mTokenCodes.get(token.getID());
    if (tc != null && tc.getCurrentCode() != null)
        tl.start(token.getType(), tc, false);
}

试试这个..

tl.bind(token, org.fedorahosted.freeotp.R.menu.token, new   PopupMenu.OnMenuItemClickListener() {
    @Override
    public boolean onMenuItemClick(MenuItem item) {

        switch (item.getItemId()) {
            case org.fedorahosted.freeotp.R.id.action_edit:

                Intent i = new Intent(ctx, EditActivity.class);
                i.putExtra(EditActivity.EXTRA_POSITION, position);
                ctx.startActivity(i);
                return true;

            case org.fedorahosted.freeotp.R.id.action_delete:

                Intent i2 = new Intent(ctx, DeleteActivity.class);
                i2.putExtra(DeleteActivity.EXTRA_POSITION, position);
                ctx.startActivity(i2);
                return true;

            default:
                return false;

        }

        return false;
    }
});

不会在弹出菜单项单击和替代活动上启动的活动打开
