标签： java android android-layout

我正在尝试从主要活动中调用新页面。主要活动包含按钮Button，onClick我正在启动新页面，如下所示

@Override
public void onClick(View arg0) {
  if(arg0.getId() == R.id.buttonSearch){
        //define a new Intent for the second Activity
        Intent intent = new Intent(this,SearchActivity.class);
        //start the second Activity
        this.startActivity(intent);
    }
}

加载新页面时我收到错误：

this.setContentView(R.layout.searchm);

以下是载入页面的代码

public class SearchActivity extends Activity   {

 Context context;    
 @Override
 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setContentView(R.layout.searchm);

LOGCAT如下：

答案 0 :(得分：2)

将您的CustomAutoCompleteTextView XML更改为

来自

<android.view.CustomAutoCompleteTextView
    ... 
    android:id="@+id/autocomplete"/>

到

<com.yourpackage.CustomAutoCompleteTextView 
    ... 
    android:id="@+id/autocomplete"/>

答案 1 :(得分：0)

从您的主要活动执行此操作以启动新的Intent，因为它位于onclick

中 
    Intent intent = new Intent(MainActivity.this,SearchActivity.class);
    //start the second Activity
    startActivity(intent);

在SearchActivity中设置内容视图就像这样...... 

    super.onCreate(savedInstanceState);
    setContentView(R.layout.searchm);

同时检查您的舱单是否已注册这两项活动。
