Question

我已经为An Edittext变量设置了一个标签。我想在文本TextWatcher afterTextChanged方法中获取该标签。但是有一个可编辑的参数而不是Edittext。

这是我的代码.....

EditText filled = new EditText(DamageCount.this);
        filled.setId(100);
        filled.setTag(5);

我希望在

中获取该标记

@Override
    public void afterTextChanged(Editable s) {
}

这种方法

------被修改---------------- 我的整个java类

public class DamageCount extends Activity {

    private Button button_next;
    static TableLayout tl = null;
    private DbWorker dbworker;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_damage_count);
        DamageCount.this
                .setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        button_next = (Button) findViewById(R.id.button_next);
        tl = (TableLayout) findViewById(R.id.show_competitor_product);
        dbworker = new DbWorker(this);
          Static_Values.arrayListdam_no = new ArrayList<DamegeItemSerialNoModel>();
        button_next.setOnClickListener(new OnClickListener() {


            @Override
            public void onClick(View v) {
                /*Intent new_one = new Intent(DamageCount.this,
                        Invoice_or_prev.class);
                startActivity(new_one);
                finish();*/
                for(DamegeItemSerialNoModel dmmm :Static_Values.arrayListdam_no)
                {
                    System.out.println("Item id is "+dmmm.getItem_id()+" serial no is "+dmmm.getSerial_no());
                }




            }

Answer 1

在Textwatcher类中创建一个构造函数，并将edittext传递给int。

public class MyTextWatcher implements TextWatcher
{
private transient EditText editText = null;
public MyTextWatcher(EditText editText)
{
super();
this.editText = editText;
}
    @Override
public void afterTextChanged(Editable arg0)
{
    // TODO Auto-generated method stub

}

@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3)
{
    // TODO Auto-generated method stub

}

@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3)
{
    // TODO Auto-generated method stub
}
}

如果您想将Editable转换为简单文字行（String），请在您的方法中使用此功能：

@Override
public void afterTextChanged(Editable s) {
    String str = s.toString();
}

将可编辑转换为Edittext
