android-textview中点击崩溃

Question

extend baseActivity，但是textview 中一个简单的onClick总是崩溃。

TextView labelName_view = (TextView) findViewById(R.id.labelName);
labelName_view.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        // animazione automatica al click
        LinearLayout contenitore_cibo_l=(LinearLayout) findViewById(R.id.bottom_container);
        LayoutParams lp = (LayoutParams) contenitore_cibo_l.getLayoutParams();
        System.out.println(lp.topMargin);
        //contenitore_cibo_l.startAnimation(makeAnimation_ordini(400, 25));
    }
});

崩溃于：

Answer 1

类型转换异常,你把RelativeLayout 强转成了ActionBar
