确定在我的应用程序我有一个字段为用户输入一个数字。我将字段设置为只接受数字。当用户点击字段时，它会弹出键盘。在键盘上(在ICS上)有一个完成按钮。我想要在键盘上的完成按钮触发提交按钮我有我的应用程序。我的代码如下。

package com.michaelpeerman.probability;

public class ProbabilityActivity extends Activity implements OnClickListener {

private Button submit;

ProgressDialog dialog;

int increment;

int heads = 0;

int tails = 0;

public void onCreate(Bundle paramBundle) {

super.onCreate(paramBundle);

setContentView(R.layout.main);

submit = ((Button) findViewById(R.id.submit));

submit.setOnClickListener(this);

}

public void onClick(View view) {

increment = 1;

dialog = new ProgressDialog(this);

dialog.setCancelable(true);

dialog.setMessage("Flipping Coin...");

dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);

dialog.setProgress(0);

int maximum = Integer.parseInt(max.getText().toString());

dialog.setMax(maximum);

dialog.show();

dialog.setOnCancelListener(new OnCancelListener(){

public void onCancel(DialogInterface dialog) {

background.interrupt();

TextView result = (TextView) findViewById(R.id.result);

result.setText("heads : " + heads + "\ntails : " + tails);

}});

background = new Thread(new Runnable() {

public void run() {

heads=0;

tails=0;

for (int j = 0; !Thread.interrupted() && j < dialog.getMax(); j++) {

int i = 1 + new Random().nextInt(2);

if (i == 1)

heads++;

if (i == 2)

tails++;

progressHandler.sendMessage(progressHandler.obtainMessage());

}

}

});

background.start();

}

Handler progressHandler = new Handler() {

public void handleMessage(Message msg) {

dialog.incrementProgressBy(increment);

if (dialog.getProgress() == dialog.getMax()) {

dialog.dismiss();

TextView result = (TextView) findViewById(R.id.result);

result.setText("heads : " + heads + "\ntails : " + tails);

}
