Question

我触摸按钮，没有任何反应。

它只显示书面文字，我要删除的行仍保留在表格中。

public void deleteword (View view) {
    db=openOrCreateDatabase("MyDB1",MODE_PRIVATE, null);
    EditText deleteword=(EditText)findViewById(R.id.deleteword);        
    String delete = deleteword.getText().toString();        
    db.execSQL("DELETE FROM Word WHERE uword='"+delete+"'");
    Toast toast = Toast.makeText(getApplicationContext(), delete, Toast.LENGTH_SHORT);
    toast.show();   
}

Answer 1

试试这个

String delete = deleteword.getText().toString();        
db.delete(Word, uword+"=?", new String[] (delete));
