Android的自定义键盘颜色 如何在自定义键盘Android中动态更改键的背景颜色或主题...

我正在使用自定义键盘应用程序我需要设置或更改键盘的背景主题或颜色.在我的应用程序中,我们可以选择不同的背景主题和不同颜色的键行.

在第一次启动应用程序时它工作正常,但下次自定义键盘显示主题时不会更改.

我正在使用此代码：

public class SoftKeyboard extends InputMethodService

implements KeyboardView.OnKeyboardActionListener {

static final boolean DEBUG = false;

/**

* This boolean indicates the optional example code for performing

* processing of hard keys in addition to regular text generation

* from on-screen interaction. It would be used for input methods that

* perform language translations (such as converting text entered on

* a QWERTY keyboard to Chinese), but may not be used for input methods

* that are primarily intended to be used for on-screen text entry.

*/

static final boolean PROCESS_HARD_KEYS = true;

private static final int SELECT_PICTURE = 101;

private KeyboardView mInputView;

private CandidateView mCandidateView;

private CompletionInfo[] mCompletions;

private Context context = SoftKeyboard.this;

private StringBuilder mComposing = new StringBuilder();

private boolean mPredictionOn;

private boolean mCompletionOn;

private int mLastDisplayWidth;

private boolean mCapsLock;

private long mLastShiftTime;

private long mMetaState;

private LatinKeyboard mSymbolsKeyboard;

private LatinKeyboard mSymbolsShiftedKeyboard;

private LatinKeyboard mQwertyKeyboard;

private LatinKeyboard mSmilyKeyboard;

private LatinKeyboard mSmilyKeyboard1;

private LatinKeyboard mCurKeyboard;

private String mWordSeparators;

/**

* Main initialization of the input method component. Be sure to call

* to super class.

*/

@Override

public void onCreate() {

super.onCreate();

mWordSeparators = getResources().getString(R.string.word_separators);

SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);

String name = preferences.getString("Name","");

Log.e("SoftKeyboard - ",""+name+"OnCreate Method Called--");

if(!name.equalsIgnoreCase(""))

{

name = name+" Sethi"; /* Edit the value here*/

}

}

这是我的设置类,我在设置或选择颜色或主题：

public class Setting extends Activity implements OnClickListener {

LinearLayout roar, edge, burst, impact, blue_theme, orange_theme,

green_theme, black_brigthness, white_brightness;

Bundle bundle;

public static boolean isblackBrightness = false;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

requestWindowFeature(Window.FEATURE_NO_TITLE);

setContentView(R.layout.setting);

// ----------UI intilisation---------------------

uiInitilisation();

}

public void uiInitilisation() {

roar = (LinearLayout) findViewById(R.id.ror_LL);

edge = (LinearLayout) findViewById(R.id.edge_LL);

burst = (LinearLayout) findViewById(R.id.burst_LL);

impact = (LinearLayout) findViewById(R.id.impact_LL);

// -------------Themes------------------------------

blue_theme = (LinearLayout) findViewById(R.id.blue_theme_LL);

orange_theme = (LinearLayout) findViewById(R.id.orange_theme_LL);

green_theme = (LinearLayout) findViewById(R.id.green_theme_LL);

// ------------Brightness----------------------------

black_brigthness = (LinearLayout) findViewById(R.id.black_brigthness_LL);

white_brightness = (LinearLayout) findViewById(R.id.white_brigthness_LL);

// --------------On Click Events-------------------

roar.setOnClickListener(this);

edge.setOnClickListener(this);

burst.setOnClickListener(this);

impact.setOnClickListener(this);

// -----------Theme-------------------------------------

blue_theme.setOnClickListener(this);

orange_theme.setOnClickListener(this);

green_theme.setOnClickListener(this);

// ------------------Brightness--------------------------

black_brigthness.setOnClickListener(this);

white_brightness.setOnClickListener(this);

}

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

switch (v.getId()) {

case R.id.ror_LL:

startActivity(new Intent(Setting.this, MainActivity.class));

break;

case R.id.edge_LL:

startActivity(new Intent(Setting.this, MainActivity.class));

break;

case R.id.burst_LL:

startActivity(new Intent(Setting.this, MainActivity.class));

break;

case R.id.impact_LL:

startActivity(new Intent(Setting.this, MainActivity.class));

break;

case R.id.blue_theme_LL:

Intent i = new Intent(Setting.this,

MainActivity.class);

i.putExtra("color", "blue");

startActivity(i);

break;

case R.id.orange_theme_LL:

Intent i2 = new Intent(Setting.this,

MainActivity.class);

i2.putExtra("color", "orange");

startActivity(i2);

break;

case R.id.green_theme_LL:

Intent i3 = new Intent(Setting.this,

MainActivity.class);

i3.putExtra("color", "green");

startActivity(i3);

break;

case R.id.black_brigthness_LL:

Intent black_britness = new Intent(Setting.this,

MainActivity.class);

black_britness.putExtra("bright", "black");

startActivity(black_britness);

SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);

SharedPreferences.Editor editor = preferences.edit();

editor.putString("Name","Harneet");

mit();

isblackBrightness = true ;

Log.e("Black--","Black=="+isblackBrightness);

break;

case R.id.white_brigthness_LL:

Intent white_britness = new Intent(Setting.this,

MainActivity.class);

white_britness.putExtra("bright", "white");

startActivity(white_britness);

isblackBrightness = false;

Log.e("white--","White=="+isblackBrightness);

SharedPreferences preferences1 = PreferenceManager.getDefaultSharedPreferences(this);

SharedPreferences.Editor editor1 = preferences1.edit();

editor1.putString("Name","Arun");

mit();

break;

}

}

}

我是否必须设置小部件,我无法做到这一点.
