在执行的onclick明文视图值 [英] clear text view value while onclick is performed

问题描述

我有明确的功能，但仍值不明确。可我知道如何解决这个问题呢？

I do have the clear function but still the value is not clear. May i know how to solve this problem ?

public class abc extends MenuActivity implements OnClickListener{


    EditText et3;
    @Override 
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.safebox_flow);


        et3 = (EditText)findViewById(R.id.EditText02);
        et3.setText(String.valueOf('0'));
        et3.setOnClickListener(this);
    }

    @Override 
    public void onClick(View v){
        //Also here check the edittext02 id thats set in the xml layout
        if(v.getId() == R.id.EditText02){
           et3.setText("");
        }
    }


}

• 我要双击它不仅可以清除。



推荐答案

您code的下面部分进入onCreate方法。

The below part of your code goes into the onCreate method.

//Here make sure **EditText02** is the id that you have declared in XML
et3 = (EditText) findViewById(R.id.EditText02);  //input type for edittext02 is number

et3.setOnClickListener(this);


public void onClick(View v){
       //Also here check the edittext02 id thats set in the xml layout
       if(v.getId() == R.id.EditText02){
          et3.setText("");
       }
}

此外，还要确保你的类实现OnClickListener

Also ensure that your class implements OnClickListener

//example below
public class MainActivity extends Activity implements OnClickListener {
