[Android] 其他class使用MainActivity元件

MainActivity.java

static MainActivity ths;

@Overrideprotected void onCreate(Bundle savedInstanceState) {
    ....
    ths = this;
    TextView showName = (TextView)findViewById(R.id.showName);

    public static MainActivity getInstance()
    {
       return ths; 
    }

    ....

    public void updateTheTextView(final String t) {
      MainActivity.this.runOnUiThread(new Runnable() {
         public void run() {
             showName.append(t);
         }
      });
    }
}




Others.java
欲使用MainActivity的texview就只要如下:


MainActivity.getInstance().updateTheTextView(strAddress);
