我正在开发一个Android应用..其中我使用SQLite数据库存储值，我有两个Button - ＆gt; 保存用于保存数据和< strong>已保存数据以显示存储数据。
当用户点击任何已保存数据行时，必须显示特定数据但我的问题是当用户按任意一行时，只显示最后一行而不是按下的行。
请检查并帮助我。
我的Activity是：
public void saveddata(View V)
{
Cursor c = db.rawQuery("SELECT * from Data", null);
int count = c.getCount();
c.moveToFirst();
TableLayout tableLayout = new TableLayout(getApplicationContext());
tableLayout.setVerticalScrollBarEnabled(true);
TableRow tableRow;
TextView textView1, textView2,textView3,textView4,textView5;
tableRow = new TableRow(getApplicationContext());
textView1 = new TextView(getApplicationContext());
textView1.setText("FirstName");
textView1.setTextColor(Color.RED);
textView1.setTypeface(null, Typeface.BOLD);
textView1.setPadding(10, 10, 10, 10);
tableRow.addView(textView1);
textView2 = new TextView(getApplicationContext());
textView2.setText("LastName");
textView2.setTextColor(Color.RED);
textView2.setTypeface(null, Typeface.BOLD);
textView2.setPadding(10, 10, 10, 10);
tableRow.addView(textView2);
tableLayout.addView(tableRow);
for(Integer j=0; j<count; j++)
{
tableRow = new TableRow(getApplicationContext());
textView3= new TextView(getApplicationContext());
textView3.setText(c.getString(c.getColumnIndex("fname")));
textView3.setClickable(true);
ett1=textView3.getText().toString();
//datas11=textView3.getText().toString();
textView4 = new TextView(getApplicationContext());
textView4.setText(c.getString(c.getColumnIndex("mname")));
textView4.setClickable(true);
ett2=textView4.getText().toString();
//datas12=textView4.getText().toString();
textView5 = new TextView(getApplicationContext());
textView5.setText(c.getString(c.getColumnIndex("lname")));
textView5.setClickable(true);
ett3=textView5.getText().toString();
//datas13=textView7.getText().toString();
textView3.setPadding(10, 10, 10,10);
textView5.setPadding(10, 10, 10, 10);
tableRow.addView(textView3);
tableRow.addView(textView5);
tableLayout.addView(tableRow);
c.moveToNext();
textView3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(MainActivity.this ,SavedDate.class);
intent.putExtra("ett1",ett1 + "");
intent.putExtra("ett2",ett2 + "");
intent.putExtra("ett3",ett3 + "");
startActivity(intent);
}
});
}
setContentView(tableLayout);
db.close();
}

嘿，这是您的新更新代码，这将对您有所帮助。
Cursor c = db.rawQuery("SELECT * from Data", null);
int count = c.getCount();
c.moveToFirst();
TableLayout table=new TableLayout;
table.setGravity(Gravity.CENTER);
table.setStretchAllColumns(true);
table.setShrinkAllColumns(true);
TableRow rowLabels = new TableRow(this);
rowLabels.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
rowLabels.setBackgroundDrawable(getResources().getDrawable(
R.xml.tablerow));
TextView srnoLabel = new TextView(this);
srnoLabel.setText("FirstName");
srnoLabel.setTypeface(Typeface.SERIF, Typeface.BOLD);
srnoLabel.setTextColor(Color.RED);
srnoLabel.setPadding(40, 5, 0, 5);
srnoLabel.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 17);
rowLabels.addView(srnoLabel);

LayoutParams.WRAP_CONTENT));
// 1 column

l_txt.setTextSize(
TypedValue.COMPLEX_UNIT_DIP, 17);
l_txt.setTextColor(Color.BLACK);
rowdata.addView(m_txt);
rowdata.setPadding(1, 1, 1, 1);
table.addView(rowLabels);
table.addView(rowdata);
}
} while (c.moveToNext());
table.setPadding(10, 10, 10, 10);
setContentView(table);
}
finally {
if (dbase != null)
// newDB.execSQL("DELETE FROM " + tableName);
c.close();
dbase.close();
}

原因是textview的click事件被动态创建的textview覆盖。因此，在for循环结束时，最终点击事件将指向最后一条记录。您可以使用自定义列表视图而不是此动态生成的表格行，并在单击时显示相应的数据。如果您想要一个示例listview和Sqlite数据库，请告诉我。
