我是Eclipse的新手,我必須通過在軟鍵盤中按下完成按鈕后清除editText中的焦點來隱藏光標.

我發現此代碼適用于其他人：

editText.setOnEditorActionListener(new OnEditorActionListener() {

@Override

public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

if(actionId==EditorInfo.IME_ACTION_DONE){

//Clear focus here from edittext

editText.clearFocus();

}

return false;

}

});

活動的代碼

package com.iprogettisti.cppp;

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.support.v7.app.ActionBarActivity;

import android.view.KeyEvent;

import android.view.LayoutInflater;

import android.view.Menu;

import android.view.MenuItem;

import android.view.View;

import android.view.ViewGroup;

import android.view.inputmethod.EditorInfo;

import android.widget.EditText;

import android.widget.TextView;

import android.widget.TextView.OnEditorActionListener;

public class VisualizzaPagina extends ActionBarActivity {

EditText edittext = (EditText) findViewById(R.id.editText1);

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

if (MainActivity.TipoPagina == 1) {

setContentView(R.layout.fragment_visualizza_pagina);

}

else if (MainActivity.TipoPagina == 2) {

setContentView(R.layout.fragment_visualizza_pagina2);

}

else if (MainActivity.TipoPagina == 3) {

setContentView(R.layout.fragment_visualizza_pagina3);

}

else if (MainActivity.TipoPagina == 4) {

setContentView(R.layout.fragment_visualizza_pagina4);

}

else if (MainActivity.TipoPagina == 5) {

setContentView(R.layout.fragment_visualizza_pagina5);

}

edittext.setOnEditorActionListener(new OnEditorActionListener() {

@Override

public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

if(actionId==EditorInfo.IME_ACTION_DONE){

//Clear focus here from edittext

edittext.setCursorVisible(false);

}

return false;

}

});

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.visualizza_pagina, menu);

return true;

}

@Override

public boolean onOptionsItemSelected(MenuItem item) {

// Handle action bar item clicks here. The action bar will

// automatically handle clicks on the Home/Up button, so long

// as you specify a parent activity in AndroidManifest.xml.

int id = item.getItemId();

if (id == R.id.action_settings) {

return true;

}

return super.onOptionsItemSelected(item);

}

/**

* A placeholder fragment containing a simple view.

*/

public static class PlaceholderFragment extends Fragment {

public PlaceholderFragment() {

}

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

View rootView = inflater.inflate(

R.layout.fragment_visualizza_pagina, container, false);

return rootView;

}

}

}

但我無法弄清楚如何得到這項工作.

我應該在哪里放置該代碼？并且在第一行“editText”中給我一個錯誤,因為沒有重新調整,我試圖給出我的edittext的唯一ID,但它沒有用.

解決方法:

試試這個

EditText edittext = (EditText) findViewById(R.id.edittext1);

edittext.setOnEditorActionListener(new OnEditorActionListener() {

@Override

public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {

if(actionId==EditorInfo.IME_ACTION_DONE){

//Clear focus here from edittext

edittext.setCursorVisible(false);

}

return false;

}

});

edittext.setOnTouchListener(new OnTouchListener() {

@Override

public boolean onTouch(View arg0, MotionEvent arg1) {

edittext.setCursorVisible(true);

return false;

}

});
