Question

在安卓编译时 出现这种错误怎么班 TextView cannot be resolved to a type!! 具体如下

package com.example.cba;import android.os.Bundle;import android.app.Activity;import android.view.Menu;public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); TextView myTextView = (TextView)findViewById(R.id.myTextView); Button myButton = (Button)findViewById(R.id.myButton); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; }}

Answer 1

你把activity_main.xml看看吧，可能是你把myTextView放置的位置不正确
