当写listview的onItemClick的方法时写Toast的参数context写成this出现can't resolve method ’make text(OnClickListene

Posted 2020-08-12 风凡

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Fruit fruit = fruitList.get(position);
                 //Toast.makeText(this,fruit.getName(),Toast.LENGTH_SHORT).show();/*出现错误，这也是错误的写法，
提示can‘t resolve method ’make text(OnClickListener，java.lang.String,int)‘*/
                Toast.makeText(MainActivity.this,fruit.getName(),Toast.LENGTH_SHORT).show();
            }
        });

 在listview的onItemClick方法中写Toast.maketext()的时候其中参数Context，不能含糊不清直接写this，而是要正确的写出MainActivity.this。
