一、布局文件showime.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:orientation="vertical">
                
        <Button android:id="@+id/ButtonIME"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="5px"
            android:text="彈出軟鍵盤輸入法" />
        
            
        <EditText android:id="@+id/EditTextIME"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="5px"
            android:text="顯示輸入法鍵盤"/>

</LinearLayout>

二、Activity，ShowIME.java文件源碼：

package org.shuxiang.test;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Looper;
import android.os.Message;
import android.os.SystemClock;
import android.view.MotionEvent;
import android.view.View;
import android.view.Window;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class ShowIME  extends Activity
{
        private EditText et;
        private Button bt;
        private static Handler messageHandler;
        
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.showime);
        
        bt = (Button) findViewById(R.id.ButtonIME);
        bt.setOnClickListener(new OnClickListener()
        {
                        @Override
                        public void onClick(View v) {
                                // TODO Auto-generated method stub
                        et.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, et.getLeft()+5, et.getTop()+5, 0));
                        et.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, et.getLeft()+5, et.getTop()+5, 0));
                        }
        });        
        et = (EditText) findViewById(R.id.EditTextIME);
        
        
        Looper looper = Looper.myLooper();
        messageHandler = new MessageHandler(looper);        
        //此處的作用是延遲1秒，然後激活點擊事件

        new Thread()

                                try
                                {
                                        wait(1000); //1秒
                                }

                        Message message = Message.obtain();
                                message.what = 1;
                    messageHandler.sendMessage(message);
                }
        }.start();        
    }
    
    class MessageHandler extends Handler
    {
        public MessageHandler(Looper looper)
        {
                super(looper);
        }
        @Override

                bt.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, et.getLeft()+5, et.getTop()+5, 0));
