这是需要点击广告的类.. ShowKamus.java

package indo.tora.kamus;

import android.app.Activity;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;



public class ShowKamus extends Activity {


    private SQLiteDatabase db = null;
    private Cursor kamusCursor = null;
    private EditText txtInggris;
    private EditText txtIndonesia;
    private DataKamus datakamus = null;
    Button translate;
    public static final String INGGRIS = "inggris";
    public static final String INDONESIA = "indonesia";



     /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        datakamus = new DataKamus(this);

        db = datakamus.getWritableDatabase();

        datakamus.createTable(db);

        datakamus.generateData(db);



        setContentView(R.layout.main);

        txtInggris = (EditText) findViewById(R.id.txtInggris);
        txtIndonesia = (EditText) findViewById(R.id.txtIndonesia);



    }



    public void getTerjemahan(View view) {

        String result = "";

        String englishword = txtInggris.getText().toString();

        kamusCursor = db.rawQuery("SELECT ID, INGGRIS, INDONESIA " + "FROM kamus where INGGRIS='" + englishword + "' ORDER BY INGGRIS", null);



        if (kamusCursor.moveToFirst()) {

            result = kamusCursor.getString(2);

            for (; !kamusCursor.isAfterLast(); kamusCursor.moveToNext()) {

                result = kamusCursor.getString(2);

                }

        }

        if (result.equals("")) {

            result = "Terjemahan Not Found";

        }

        txtIndonesia.setText(result);



    }

    @Override

    public void onDestroy() {

        super.onDestroy();

        kamusCursor.close();

        db.close();

    }

}

提前感谢..

Answer 1

看起来您的KamusActivity使用main.xml作为内容视图，但您没有将getTerjemahan添加到此类。

所以你应该添加

 public void getTerjemahan(View view) {
    //your code
 }

到KamusActivity。

需要onClick处理程序来查看
