togglebuttonandroid
Ⅰ android編程問題： ToggleButton toggleButton = (ToggleButton)this.findViewById(R.id.ToggleButton1);
兩句話的意思是相同的,只不過findView把前面的this隱掉.當然可以直接使用,不會出現你所說的Edit或者Image能用,
Ⅱ android如何去掉togglebutton上面自動顯示的字「on」「off」就像下面按鈕上的「on」，是默認顯示的。
Togglebutton通過一個帶有亮度指示同時默認文本為「ON」或「OFF」的按鈕顯示選中/未選中狀態。
提示文字的設置方式:
1.在xml中直接設置
android:textOn=""設置按鈕未選中時顯示的文本。
android:textOff=""設置按鈕選中時顯示的文本。
2.在java代碼中設置:
public void setTextOff (CharSequence textOff)設置按鈕未選中時顯示的文本。
public void setTextOn (CharSequence textOn)設置按鈕選中時顯示的文本。
Ⅲ 有沒有什麼方法能夠快速，實時的獲取android手機的電量值
這個是獲取android電量的DEMO：
package com.android.batterywaster;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.BatteryManager;
import android.os.Bundle;
import android.os.PowerManager;
import android.view.View;
import android.widget.CheckBox;
import android.widget.TextView;
import java.text.DateFormat;
import java.util.Date;
/**
* So you thought sync used up your battery life.
*/
public class BatteryWaster extends Activity {
TextView mLog;
DateFormat mDateFormat;
IntentFilter mFilter;
PowerManager.WakeLock mWakeLock;
SpinThread mThread;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set the layout for this activity. You can find it
// in res/layout/hello_activity.xml
setContentView(R.layout.main);
findViewById(R.id.checkbox).setOnClickListener(mClickListener);
mLog = (TextView)findViewById(R.id.log);
mDateFormat = DateFormat.getInstance();
mFilter = new IntentFilter();
mFilter.addAction(Intent.ACTION_BATTERY_CHANGED);
mFilter.addAction(Intent.ACTION_BATTERY_LOW);
mFilter.addAction(Intent.ACTION_BATTERY_OKAY);
mFilter.addAction(Intent.ACTION_POWER_CONNECTED);
PowerManager pm = (PowerManager)getSystemService(POWER_SERVICE);
mWakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "BatteryWaster");
mWakeLock.setReferenceCounted(false);
}
@Override
public void onPause() {
stopRunning();
}
View.OnClickListener mClickListener = new View.OnClickListener() {
public void onClick(View v) {
CheckBox checkbox = (CheckBox)v;
if (checkbox.isChecked()) {
startRunning();
} else {
stopRunning();
}
}
};
void startRunning() {
log("Start");
registerReceiver(mReceiver, mFilter);
mWakeLock.acquire();
if (mThread == null) {
mThread = new SpinThread();
mThread.start();
}
}
void stopRunning() {
log("Stop");
unregisterReceiver(mReceiver);
mWakeLock.release();
if (mThread != null) {
mThread.quit();
mThread = null;
}
}
void log(String s) {
mLog.setText(mLog.getText() + "\n" + mDateFormat.format(new Date()) + ": " + s);
}
BroadcastReceiver mReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
String title = action;
int index = title.lastIndexOf('.');
if (index >= 0) {
title = title.substring(index + 1);
}
if (Intent.ACTION_BATTERY_CHANGED.equals(action)) {
int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int icon = intent.getIntExtra(BatteryManager.EXTRA_ICON_SMALL,-1);
log(title + ": level=" + level + "\n" + "icon:" + icon);
} else {
log(title);
}
}
};
class SpinThread extends Thread {
private boolean mStop;
public void quit() {
synchronized (this) {
mStop = true;
}
}
public void run() {
while (true) {
synchronized (this) {
if (mStop) {

wipe電池如下：
1、把電池充滿，充滿滿的，在開機狀態下沖到滿，然後拔下充電器，手機關機，再插上充電器充電，直至再次顯示充滿，拔下充電器，開機再充電，這樣反復幾次就能把電池充到盡量滿的狀態。
2、然後關機，開機進入Recovery模式。
選擇advanced（高級功能） -> wipe battery stats（清空電池狀態）->yes（是）
然後++++ Go Back（返回上級） ++++ --> - reboot system now（重啟系統） -
Ⅳ android軟體開發里邊 togglebutton使用setChecked問題
if (volReturned.equals("On")){
/*tbtnvol.setChecked(true);*/
tbtnvol.setSelected(boolT);
}else{
tbtnvol.setSelected(boolF);
}
if (vibReturned.equals("On")){
tbtnvib.setSelected(boolT);
}else{
tbtnvib.setSelected(boolF);
}
Ⅳ android怎麼實現自動接聽和掛斷電話功能
android 實現來電自動接聽和自動掛斷的方法：
第一步：准備應用環境需要的系統包和aidl文件。
（1）在應用中創建包:android.telephony
將android系統框架下的\framework\telephony\java\android\telephony目錄中的NeighboringCellInfo.aidl文件復制到上面創建的包（android.telephony ）中；
（2）在應用中創建包:com.android.internal.telephony
將android系統框架下的\framework\telephony\java\com\android\internal\telephony目錄中的ITelephony.aidl文件復制到上面創建的包（com.android.internal.telephony ）中。
第二步：創建一個獲取ITelephony的方法
PhoneUtils.java
package com.zhouzijing.android.demo;
import java.lang.reflect.Method;
import com.android.internal.telephony.ITelephony;
import android.telephony.TelephonyManager;
public class PhoneUtils {
/**
* 根據傳入的TelephonyManager來取得系統的ITelephony實例.
* @param telephony
* @return 系統的ITelephony實例
* @throws Exception
*/
public static ITelephony getITelephony(TelephonyManager telephony) throws Exception {
Method getITelephonyMethod = telephony.getClass().getDeclaredMethod("getITelephony");
getITelephonyMethod.setAccessible(true);//私有化函數也能使用
return (ITelephony)getITelephonyMethod.invoke(telephony);
}
}
第三步：創建電話廣播攔截器
MyPhoneBroadcastReceiver.java
package com.zhouzijing.android.demo;
import com.android.internal.telephony.ITelephony;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;
public class MyPhoneBroadcastReceiver extends BroadcastReceiver {
private final static String TAG = MyPhone.TAG;
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
Log.i(TAG, "[Broadcast]"+action);
//呼入電話
if(action.equals(MyPhone.B_PHONE_STATE)){
Log.i(TAG, "[Broadcast]PHONE_STATE");
doReceivePhone(context,intent);
}
}
/**
* 處理電話廣播.
* @param context
* @param intent
*/
public void doReceivePhone(Context context, Intent intent) {
String phoneNumber = intent.getStringExtra(
TelephonyManager.EXTRA_INCOMING_NUMBER);
TelephonyManager telephony = (TelephonyManager)context.getSystemService(
Context.TELEPHONY_SERVICE);
int state = telephony.getCallState();
switch(state){
case TelephonyManager.CALL_STATE_RINGING:
Log.i(TAG, "[Broadcast]等待接電話="+phoneNumber);
try {
ITelephony iTelephony = PhoneUtils.getITelephony(telephony);
iTelephony.answerRingingCall();//自動接通電話
//iTelephony.endCall();//自動掛斷電話
} catch (Exception e) {
Log.e(TAG, "[Broadcast]Exception="+e.getMessage(), e);
}
break;
case TelephonyManager.CALL_STATE_IDLE:
Log.i(TAG, "[Broadcast]電話掛斷="+phoneNumber);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.i(TAG, "[Broadcast]通話中="+phoneNumber);
break;
}
}
}
第四部：注冊電話廣播攔截器
MyPhone.java
package com.zhouzijing.android.demo;
import android.app.Activity;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.View;
public class MyPhone extends Activity {
public final static String TAG = "MyPhone";
public final static String B_PHONE_STATE = TelephonyManager.ACTION_PHONE_STATE_CHANGED;
private MyPhoneBroadcastReceiver mBroadcastReceiver;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_phone);
}
//按鈕1-注冊廣播
public void registerThis(View v) {
Log.i(TAG, "registerThis");
mBroadcastReceiver = new MyPhoneBroadcastReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(B_PHONE_STATE);
intentFilter.setPriority(Integer.MAX_VALUE);
registerReceiver(mBroadcastReceiver, intentFilter);
}
//按鈕2-撤銷廣播
public void unregisterThis(View v) {
Log.i(TAG, "unregisterThis");
unregisterReceiver(mBroadcastReceiver);
}
}
第5步：在AndroidManifest.xml配置許可權
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
<uses-permission android:name="android.permission.CALL_PHONE"/>
其中：
iTelephony.answerRingingCall();//自動接通電話
必須有許可權 android.permission.MODIFY_PHONE_STATE
iTelephony.endCall();//自動掛斷電話
必須有許可權 android.permission.CALL_PHONE。
