Android的编程，一个小问题。 [英] Android programming, a little issue.

问题描述

我收到下一个括号中的红色花体这个时候，告诉我插入EnumBody完成EnumDeclaration

这是发生在这个code中的最后一行，在最后括号;

 如果（位置== 3）{
            意向意图=新的意图（Main.this，Progress.class）;
            Main.this.startActivity（意向）; }}}）
 

下面是我的整个活动code;

 包com.example.gymbuddy;

进口android.os.Bundle;
进口android.app.Activity;
进口android.content.Intent;
进口android.view.View;
进口android.view.View.OnClickListener;
进口android.widget.AdapterView;
进口android.widget.AdapterView.OnItemSelectedListener;
进口android.widget.ArrayAdapter;
进口android.widget.Spinner;

公共类主要扩展活动{

@覆盖
公共无效的onCreate（包savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.activity_main）;

    findViewById（R.id.button2）.setOnClickListener（新handleButton2（））;
    findViewById（R.id.button3）.setOnClickListener（新handleButton3（））;
    findViewById（R.id.button4）.setOnClickListener（新handleButton4（））;

    微调微调=（微调）findViewById（R.id.spinner）;
    ArrayAdapter＆LT; CharSequence的＆GT;适配器= ArrayAdapter.createFromResource（
            对此，R.array.work_array，android.R.layout.simple_spinner_item）;
    adapter.setDropDownViewResource（android.R.layout.simple_spinner_dropdown_item）;
    spinner.setAdapter（适配器）;

    }

类handleButton2实现OnClickListener {
    公共无效的onClick（视图v）{
        意向意图=新的意图（Main.this，Benchmark.class）;
        startActivity（意向）; }}

类handleButton3实现OnClickListener {
    公共无效的onClick（视图v）{
        意向意图=新的意图（Main.this，Progress.class）;
        startActivity（意向）; }}

类handleButton4实现OnClickListener {
    公共无效的onClick（视图v）{
        意向意图=新的意图（Main.this，Settings.class）;
        startActivity（意向）; }} @

spinner.setOnItemSelectedListener（新OnItemSelectedListener（）{
    公共无效onItemSelected（适配器视图＆LT;＆GT; parentView，查看selectedItemView，INT位置，长的id）{
        如果（位置== 1）{
            意向意图=新的意图（Main.this，Upperbody.class）;
            Main.this.startActivity（意向）; }
        如果（位置== 2）{
            意向意图=新的意图（Main.this，Settings.class）;
            Main.this.startActivity（意向）; }
        如果（位置== 3）{
            意向意图=新的意图（Main.this，Progress.class）;
            Main.this.startActivity（意向）; }}}）

}
 

解决方案

这是实际的code？难道是额外的@字符类handleButton4的结束？

 类handleButton4实现OnClickListener {
    公共无效的onClick（视图v）{
        意向意图=新的意图（Main.this，Settings.class）;
        startActivity（意向）; }} // //＆LT; -------这
 

I'm getting the red squiggle under a parenthesis this time, telling me "insert "EnumBody" to complete EnumDeclaration"

It is happening on the last line of this code, on the very last parenthesis;

if (position == 3){ 
            Intent intent = new Intent(Main.this, Progress.class); 
            Main.this.startActivity(intent); } } } )

Here is my whole activity code;

package com.example.gymbuddy;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Spinner;

public class Main extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    findViewById(R.id.button2).setOnClickListener(new handleButton2());
    findViewById(R.id.button3).setOnClickListener(new handleButton3());
    findViewById(R.id.button4).setOnClickListener(new handleButton4());

    Spinner spinner = (Spinner) findViewById(R.id.spinner);
    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
            this, R.array.work_array, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);

    }

class handleButton2 implements OnClickListener {
    public void onClick(View v) {
        Intent intent = new Intent(Main.this, Benchmark.class);
        startActivity(intent);  } }

class handleButton3 implements OnClickListener {
    public void onClick(View v) {
        Intent intent = new Intent(Main.this, Progress.class);
        startActivity(intent);  } }

class handleButton4 implements OnClickListener {
    public void onClick(View v) {
        Intent intent = new Intent(Main.this, Settings.class);
        startActivity(intent);  } }@

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
        if (position == 1){
            Intent intent = new Intent(Main.this, Upperbody.class);
            Main.this.startActivity(intent); }
        if (position == 2){
            Intent intent = new Intent(Main.this, Settings.class);
            Main.this.startActivity(intent); }
        if (position == 3){
            Intent intent = new Intent(Main.this, Progress.class);
            Main.this.startActivity(intent); } } } )

}

解决方案

Is this the actual code? Could it be the additional "@" character at the end of class handleButton4?

class handleButton4 implements OnClickListener {
    public void onClick(View v) {
        Intent intent = new Intent(Main.this, Settings.class);
        startActivity(intent);  } }@ // <------- this
