Java 很遗憾，您的应用程序已停止

我一直收到这条消息，不幸的是你的应用程序在不知道原因的情况下停止了

这是我的主要任务

import android.app.ActionBar;
import android.app.Activity;
import android.app.SearchManager;
import android.content.Context;
import android.os.Bundle;
import android.support.v7.widget.SearchView;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.TextView.OnEditorActionListener;
import android.widget.Toast;

public class MainActivity extends Activity {
private ActionBar actionBar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    try {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);
    actionBar = getActionBar();
    // add the custom view to the action bar
    actionBar.setCustomView(R.layout.actionbar_view);
    EditText search = (EditText) actionBar.getCustomView().findViewById(R.id.searchfield);
    search.setOnEditorActionListener(new OnEditorActionListener() {

      @Override
    public boolean onEditorAction(TextView v, int actionId,
          KeyEvent event) {

        return true;
      }
    });
    actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM
        | ActionBar.DISPLAY_SHOW_HOME);

    }
    catch (NullPointerException ex)
    {
        throw new IllegalStateException("null property", ex);
    }
}

@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);





    // Associate searchable configuration with the SearchView
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.search_action)
            .getActionView();
    //searchView.setSearchableInfo(searchManager
    //      .getSearchableInfo(getComponentName()));
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    if (id == R.id.search_action)
        return true;
    return super.onOptionsItemSelected(item);

}
}

问题的根源是主要的 我没有一个代码错误 而且这从来都不是支架的问题 我还尝试了从清单中更改主题的解决方案

这是我的舱单

因为您的目标是API级别11以上，所以应该替换

导入android.support.v7.widget.SearchView

借

导入android.widget.SearchView

另请参阅这篇关于操作栏搜索视图的文章

根据logcat，您的错误在于菜单文件
R.menu.main

改变

 android:icon="@+id/ic_action_search"

到

任何logcat信息？？此行的代码是什么
MainActivity.java:64
请帮助任何人？Panther我刚刚添加了一个新日志请阅读it@Marta我刚刚添加了我的drawable，它显示了一个图标的未定义drawable状态，我如何解决它？蒙克布罗克先生，我做了你说的但没用，请帮帮我？@Marta非常感谢你们所有人试图帮助我，我真的很感激
