いくつかのラジオ ボタンを使用して、AlertDialog で共有設定を設定できます。
public void ShowRadioDialog() {
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
final SharedPreferences.Editor editor = preferences.edit();
SharedPreferences choiceSettings = getSharedPreferences("currentChoice", 0);
final int[] currentChoice = {choiceSettings.getInt("currentChoice", 0)};
final CharSequence[] items={"Rosso","Verde","Blu","Giallo","Arancione"};
AlertDialog.Builder builder=new AlertDialog.Builder(this);
builder.setTitle("Seleziona un colore");
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
@SuppressLint("NewApi")
@Override
public void onClick(DialogInterface dialog, int which) {
if (index == 1) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
getWindow().setStatusBarColor(MainActivity.this.getResources().getColor(R.color.redDark));
toolbar.setBackgroundColor(MainActivity.this.getResources().getColor(R.color.red));
Toast.makeText(MainActivity.this, "Rosso OK", Toast.LENGTH_SHORT).show();
Log.i("Colors", "Rosso Ok");
}
} else if (index ==2) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
getWindow().setStatusBarColor(MainActivity.this.getResources().getColor(R.color.green_welcome));
toolbar.setBackgroundColor(MainActivity.this.getResources().getColor(R.color.green));
}
} else if (index == 3){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
getWindow().setStatusBarColor(MainActivity.this.getResources().getColor(R.color.primary_dark_blue));
toolbar.setBackgroundColor(MainActivity.this.getResources().getColor(R.color.primary_blue));
}
} else if (index == 4){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
getWindow().setStatusBarColor(MainActivity.this.getResources().getColor(R.color.yellowDark));
toolbar.setBackgroundColor(MainActivity.this.getResources().getColor(R.color.yellow));
}
} else if (index == 5){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
getWindow().setStatusBarColor(MainActivity.this.getResources().getColor(R.color.dark_orange));
toolbar.setBackgroundColor(MainActivity.this.getResources().getColor(R.color.main_orange));
}
}
SharedPreferences preferences = getSharedPreferences("myPref", getApplicationContext().MODE_PRIVATE);
Editor editor = preferences.edit();
editor.putInt("choice", index);
editor.commit();
}
});
builder.setSingleChoiceItems(items,-1, new DialogInterface.OnClickListener() {
@SuppressLint("NewApi")
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
if ("Rosso".equals(items[which])) {
index = 1;
} else if ("Verde".equals(items[which])) {
index = 2;
} else if ("Blu".equals(items[which])) {
index = 3;
} else if ("Giallo".equals(items[which])) {
index = 4;
} else if ("Arancione".equals(items[which])) {
index = 5;
}
}
});
builder.show();
}
MainActivity の onCreate では、次の方法で共有設定をフェッチします。
SharedPreferences preferences = getSharedPreferences("myPref", getApplicationContext().MODE_PRIVATE);
index = preferences.getInt("choice",-1);
Log.i("Shared", "Y "+index);
ログは正しいです！index保存された正しい位置にあります。ただし、ダイアログの条件は実行しません。ステータスバーとツールバーの色を変えたい。ダイアログでタップするとラジオボタンが機能しますが、アプリを終了してから再度開くと、色がデフォルトに戻ります。だけどラジオボタンの状態は保存されてる..なんか変だなぁ..
