所以我有这些代码

definisi.java

package com.example.kamusinggris_indonesiaidiom;

import android.app.ActionBar;

public class Definisi extends Activity {

@Override

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

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB){
        ActionBar actionBar = getActionBar();
        actionBar.setDisplayHomeAsUpEnabled(true);
}
    Uri uri = getIntent().getData();
    Cursor kursor = managedQuery(uri, null, null, null, null);

    if (kursor == null) {
        finish();
    } else {
        kursor.moveToFirst();

        TextView kata = (TextView) findViewById(R.id.kata);
        TextView definisi= (TextView) findViewById(R.id.definisi);

        int wIndex = kursor.getColumnIndexOrThrow(Database.KATA);
        int dIndex = kursor.getColumnIndexOrThrow(Database.DEFINISI);

        kata.setText(kursor.getString(wIndex));
        definisi.setText(kursor.getString(dIndex));
}       }
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB){
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        searchView.setIconifiedByDefault(false);
    }

    return true;
}   
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.search:
            onSearchRequested();
            return true;
        case android.R.id.home:
            Intent a = new Intent(this, Main.class);
            a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(a);
            return true;
        default:
            return false;
    }
}
}

它是一个字典，所以当点击列表视图上的搜索建议时，它应该打开definisi.java并显示定义。但是我在这里得到的是当我点击搜索建议时它显示了main.java（它只是回到上一个活动）。意图部分出了什么问题？请帮帮我

Answer 1

在intent

中使用已通过的onNewIntent变量

 protected void onNewIntent(Intent intent) {
        handleIntent(intent);
 }

您还应该从handleIntent方法

中删除对handleIntent的来电

Android Intent不起作用
