java - Android Intent 不起作用

Question

所以我有这些代码

main.java

    list = (ListView) findViewById(R.id.list);

}

        handleIntent(getIntent());
         }

    // TODO Auto-generated method stub
    handleIntent(intent);

     if (Intent.ACTION_VIEW.equals(intent.getAction())) {
            Intent wordIntent = new Intent(this, Definisi.class);
            wordIntent.setData(intent.getData());
            startActivity(wordIntent);
        } else if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);
            showResults(query);
}


}
    private void showResults(String query) {
    // TODO Auto-generated method stub
    Cursor cursor = managedQuery(Provider.CONTENT_URI, null, null,

definisi.java

package com.example.kamusinggris_indonesiaidiom;

import android.app.ActionBar;
import android.app.Activity;
import android.app.SearchManager;
import android.content.Context;

    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;
    }
}
}

它是一本字典，因此当单击 ListView 上的搜索建议时，它应该打开 definisi.java 并显示定义。但我得到的是，当我单击搜索建议时，它显示了 main.java (它只是返回到上一个 Activity )。 Intent 部分出了什么问题？请帮助我

Answer 1

在onNewIntent中使用传递的intent变量

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

您还应该从 handleIntent 方法中删除对 handleIntent 的调用
