Question

我正在创建一个应用，当用户选择支票时，会调用第二个活动。但是，当调用第二个活动时，我的应用程序崩溃并且日志cat在我的paycheckactivity oncreate方法上显示错误。

第一项活动

public class TableListActivity extends Activity {
private ListView mListView;
private TableListAdapter mAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_table_list);

    mListView = (ListView)findViewById(R.id.listView);
    mAdapter = new TableListAdapter(this, DataStore.CHECKS);
    mListView.setAdapter(mAdapter);
    mListView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            Intent intent = new Intent (TableListActivity.this, PayCheckActivity.class);
            intent.putExtra(PayCheckActivity.Extra_check, arg2);
            startActivity(intent);
        }
    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.table_list, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();

        if (id == R.id.action_refresh) {
            Toast.makeText(this, "Refresh", Toast.LENGTH_SHORT).show();
        return true;
        }
        return super.onOptionsItemSelected(item);}}

第二项活动

public class PayCheckActivity extends Activity {
    public static final String Extra_check= "abc";

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.paycheck);
    }
}

logcat的

Answer 1

在这里，你得到两个Exception ...

＃android.view.InflateException：当您尝试inflate您的视图/ XML时，会导致它。由于您使用的是CustomAdapter，因此您在onCreateView()方法中夸大了列表项的XML以及导致问题的XML ... LogCat直接将其指示为...

Caused by: android.view.InflateException: Binary XML file line #15: Error inflating class br

＃java.lang.ClassNotFoundException：由于您试图将HTML标记<br></br>置于XML Android XML不支持的XML中，因此导致该问题。 LogCat清楚地表明您正在使用此邮件的<br>标记...

Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.br"

在名为br的android中没有视图...因此将其从XML中删除...您的问题将得到解决。

Answer 2

在“application”标签下的AndroidManifest.xml文件中提及活动名称，如下所述：

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.TableListActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
     <activity
        android:name="com.example.PayCheckActivity"
        android:label="@string/app_name" >
        </activity>

</application>

如果仍然显示错误，请告诉错误。

Answer 3

看起来您已经为PayCheckActivity复制了粘贴（就像我也是:) :) onCreate，因此您在那里缺少 @Override 关键字。

这个onCreate（）不再是Activity重写方法，而是错误。

就这样做，

public class PayCheckActivity extends Activity{
    public static final String Extra_check= "abc";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.paycheck);
    } 
}

希望这会有所帮助。：）
