具有两个功能的Android按钮 [英] Android button having two functions

问题描述

我需要有一个假定具有两个功能的按钮.

I need to have a button that is suppose to have two functions.

如果我点击一次，它将转到下一页.如果我按住按钮，它将允许我编辑按钮上的文本.

If I tap on it once, it will go to the next page. If I hold down on the button, it will allow me to edit the text on the button.

点击该按钮可以转到下一页，但是如果我按住该按钮，该如何实现允许我更改文本的第二个功能呢?

The button is able to go to the next page upon tapping on it, but how do I implement the second function which allows me to change the text If I hold down the button?

有人知道吗?

java代码

public class MainActivity extends Activity {
    Button button1;
    Button button2;
    Button button3;
    Handler h;
    private Socket socket;
    private boolean mInSettingsMode;
    private static final int SERVERPORT = 5000;
    private static final String SERVER_IP = "192.168.43.83";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        new Thread(new ClientThread()).start();
        // living button click start
        button1 = (Button) findViewById(R.id.btnliving);
        button1.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                h = new Handler();
                h.postDelayed(irun, 0);
            }
        });

        button2 = (Button) findViewById(R.id.btnbed);
        button2.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                h = new Handler();
                h.postDelayed(irun2, 0);
            }
        });

        button3 = (Button) findViewById(R.id.btndin);
        button3.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                h = new Handler();
                h.postDelayed(irun3, 0);
            }
        });
    }

    Runnable irun = new Runnable() {
        @Override
        public void run() {
            // TODO Auto-generated method stub
            Intent i = new Intent(MainActivity.this, living.class);
            startActivity(i);
            finish();
            overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
        }
    };

    Runnable irun2 = new Runnable() {
        @Override
        public void run() {
            // TODO Auto-generated method stub
            Intent i = new Intent(MainActivity.this, bed.class);
            startActivity(i);
            finish();
            overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
        }
    };

    Runnable irun3 = new Runnable() {
        @Override
        public void run() {
            // TODO Auto-generated method stub
            Intent i = new Intent(MainActivity.this, din.class);
            startActivity(i);
            finish();
            overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
        }
    };

    /*
     * @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the
     * menu; this adds items to the action bar if it is present.
     * getMenuInflater().inflate(R.menu.main, menu); return true; }
     */
    class ClientThread implements Runnable {
        @Override
        public void run() {
            try {
                InetAddress serverAddr = InetAddress.getByName(SERVER_IP);
                // new Thread(new ClientThread()).start();
                socket = new Socket(serverAddr, SERVERPORT);
            } catch (UnknownHostException e1) {
                e1.printStackTrace();
            } catch (IOException e1) {
                e1.printStackTrace();
            }
        }
    }
}

xml代码

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

 android:layout_width="match_parent"
 android:layout_height="match_parent"

 <Button 
 android:id="@+id/btnliving"

 android:layout_height="wrap_content"
 android:text="Light Control"

 <Button 
 android:id="@+id/btnbed"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="Fan Control"

 <Button

 </LinearLayout>

推荐答案

您可以将第二个功能设置为setOnLongClickListener:

You can set second function as a setOnLongClickListener as:

button.setOnLongClickListener(new OnLongClickListener() { 
        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub
            //change text here
            return true;
        }
    });

第一个函数与setOnclickListener相同:

and first function is same setOnclickListener as:

button.setOnClickListener(new View.OnClickListener() {
             public void onClick(View v) {
                 // Perform action on click
             }
         });
