我正在尝试将 String[] 发送到另一个类的内部类中的线程(如果有意义的话)。然后我想对 String[] 做一些工作,然后将其输出回 UI。但我不确定该怎么做?我还使用什么消息,以便我可以控制将在 UI 中执行的内容。
这是我的MainActivity
:
public class MainActivity extends Activity implements OnClickListener {
EditText cl;
TextView info;
Button enter;
Button line;
Button arc;
Line callLine = new DrawingUtils.Line();
Enter callEnter = new DrawingUtils.Enter();
Arc callArc = new DrawingUtils.Arc();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
info = (TextView) findViewById(R.id.info);
enter = (Button) findViewById(R.id.enter);
line = (Button) findViewById(R.id.line);
arc = (Button) findViewById(R.id.arc);
cl = (EditText) findViewById(R.id.editText1);
Handler uiHandler = new Handler() {
public void handleMessage(Message msg) {
switch (msg.what) {
}
}
};
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.enter:
String in = cl.getText().toString();
String[] Input = in.split(",");
// I would like to send Input[] to the line Thread in DrawingUtils
callEnter.start();
break;
case R.id.line:
callLine.start();
break;
case R.id.arc:
callArc.start();
break;
}
};
}
继承人的另一个类具有 in 类Thread
:
public class DrawingUtils {
// Thread classes for buttons
public static class Line extends Thread {
Thread line = new Thread() {
public void run() {
Looper.prepare();
Handler lineHandler = new Handler() {
public void handleMessage(Message msg) {
// How to get Input from Enter button to use in thread
}
};
Looper.loop();
// Then I need to do some work
// Then Send the worked data back to the uiHandler in
// oncreate().
}
};
}
我正在使用处理程序,因为它们似乎对我的代码有用。当有人点击 Line 时,它会设置一个 textview 说 (INPUT POINT1) 然后线程将等待,当用户输入 x,y,z 到 edittext 并单击 Enter 输入将被放入一个字符串中,然后用逗号分隔并放入放入一个字符串数组,该数组将被线线程处理,然后在 Enters 代码的末尾调用 notifyAll() 以允许线线程继续并请求下一个输入。在行线程结束时,它将被处理回 UI 线程
