本來我是想要做一個每隔一秒添加一個文字的文本框，本來我想利用線程中的sleep方法做到，可是線程創(chuàng)建后無法運行，不填語句還好，填了以后點擊按鈕就閃退，請問這是怎么回事？ import android.app.*; import android.os.*; import android.view.View; import android.widget.*; import android.view.View.*; public class MainActivity extends Activity { public TextView viw; public Button buttob1; ??? public boolean xc=false; public Thread ti; /*spak to=new spak();*/ ??? @Override ??? protected void onCreate(Bundle savedInstanceState) ??? { ??????? super.onCreate(savedInstanceState); ??????? setContentView(R.layout.main); ??? buttob1=(Button) findViewById(R.id.button1); buttob1.setOnClickListener(new OnClickListener() { @Override public void onClick(View p1) { // TODO: Implement this method ther t=new ther(); t.start(); ???? } ????? }); ??? } public class ther extends Thread ??? { public void run(){ //這里填下面這一段會閃退…… viw.append("你好"); } } ???? }
