mt6735 FM菜单选项中添加手动设置频率

[DESCRIPTION]
FM菜单中不可以手工输入电台名称，需要增加该菜单以实现：手动输入频率并跳转到该频率
[SOLUTION]
一、在mediatek\packages\apps\FMRadio\res\Layout中新增fm_manualinput_layout.xml文件，代码如下：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fm_manualinput_layout"
androidrientation="vertical"
android:layout_width="286dp"
android:layout_height="wrap_content">
<TextView
android:id="@+id/fm_manualinput_title_bar"
style="?android:attr/windowTitleStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="53dp"
android:padding="10dp"
android:singleLine="true"
android:gravity="center|left"
android:text="@string/dlg_manual_input_title"/>
<View
android:id="@+id/divider"
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#31b6e7" />
<LinearLayout
android:id="@+id/contentEdit"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="68dp"
android:gravity="center">
<EditText
android:id="@+id/fm_edit_text"
android:layout_width="265dp"
android:layout_height="wrap_content"
android:singleLine="true"
android:numeric="integer"
android:maxLength="80"/>
</LinearLayout>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#424542" />
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="@+id/fm_manualinput_btn_discard"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/btn_discard_manualinput"/>
<View
android:layout_width="1dp"
android:layout_height="match_parent"
android:background="#424542" />
<Button
android:id="@+id/fm_manualinput_btn_sure"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/btn_save_manualinput"/>
</LinearLayout>
</LinearLayout>

二、在mediatek\packages\apps\FMRadio\res\values的strings.xml文件中增加如下：
<string name="dlg_manual_input_title">Manual input</string>
<string name="btn_discard_manualinput">Discard</string>
<string name="btn_save_manualinput">Sure</string>
<string name="edit_manualinput_name_hint">Type channel here</string>

三、修改mediatek\packages\apps\FMRadio\res\menu\fm_menu.xml文件，
添加menu：
<item android:id="@+id/fm_manual_input"
android:title="fm_manual_input"
android:enabled="false"/>

四、修改FMRadioActivity.java
(1)在开头处：public class FMRadioActivity extends Activity implements…FMManualInputDialogFragment.OnManualInputDialogCLIckListener//增加该行

(2) 在开头全局变量定义处增加：
private static final String SEARCH = "Search";
private static final String MANUAL_INPUT = "ManualInput";

(3) public boolean onOptionsItEMSelected(MenuItem item)
case R.id.fm_menu:
……
if (isPlaying) {
menu.findItem(R.id.fm_search).setEnabled(true);
//添加以下
menu.findItem(R.id.fm_manual_input).setEnabled(true);
//添加以上
}

(4) private void refreshPopupMenuItem(boolean enabled) {
……
}
if (null ！= mPopupMenu) {
//添加以下
menu.findItem(R.id.fm_manual_input).setEnabled(enabled);
//添加以上
}
}

(5) public boolean onMenuItemClick(MenuItem item) {
LogUtils.d(TAG, "onMenuItemClick:" + item.getItemId());
switch (item.getItemId()) {
……
//添加以下
case R.id.fm_manual_input:
mMenuItempower.setEnabled(false);
mMenuItemChannelList.setEnabled(false);
mMenuItemOverflow.setEnabled(false);
showManualInputDialog();
//添加以上
……
}

(6) 增加该段代码：
public void showManualInputDialog() {
int freq = mService.getFrequency();
if (FMRadioUtils.isValidStation(freq)) {
LogUtils.d(TAG, "frequency frequency isValid Station");}
else
freq=FMRadioUtils.LOWEST_STATION;
FMManualInputDialogFragment newFragment = new FMManualInputDialogFragment(freq);
newFragment.show(mFragmentManager,MANUAL_INPUT);
mFragmentManager.executePendingTransactions();
}

(7) 增加该段代码：
private void dismissManualInputDialog() {
FragmentTransaction ft = mFragmentManager.beginTransaction();
Fragment fragment = mFragmentManager.findFragmentByTag(MANUAL_INPUT);
if (null ！= fragment) {
ft.remove(fragment);
ft.coMMItAllowingStateLoss();
}
}

(8) 增加该段代码：
public void onManualInputClick(int editName) {
tuneToStation(editName);
}

(9) public void onPause() {
if (null ！= df && df.getShowsDialog()) {
……
//添加以下
dismissManualInputDialog();
//添加以上
}
……
}

五、在mediatek\packages\apps\FMRadio\src目录下增加FMManualInputDialogFragment.java文件
，代码如下：
package com.mediatek.FMRadio; import android.app.Activity;
import android.app.Dialog;
import android.app.DialogFragment;

import android.widget.Toast;
import com.mediatek.FMRadio.dialogs.SearchChannelsDialog;
import com.mediatek.common.featureoption.FeatureOption;
import java.io.File;

private String mEditNameToSure = null; //recording file to save name

private OnManualInputDialogClickListener mListener = null;
int mOldChannel=0;
public FMManualInputDialogFragment(int freq) {
mOldChannel=freq;
}
@Override
