一修改系统文字大小：
- 系统文字太小，需要修改文字大小修改如下

- 设置-显示-显示大小和文字进入 这里可以拖拽实现大小。这里要说的是，点击重置按钮，文字大小重置系统默认值，而非1中的大小，这里要修改成和自定义的大小一致，修改如下：

二：修改显示大小：
1) 先定义
//framework/base/packages/SettingsProvider/res/values/defaults.xml<resources>+ <string name="def_display_density">170</string><bool name="def_dim_screen">true</bool><integer name="def_screen_off_timeout">60000</integer><integer name="def_sleep_timeout">-1</integer>
2）再加载
//framework/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.javaprivate void loadSystemSettings(SQLiteDatabase db) {SQLiteStatement stmt = null;try {stmt = db.compileStatement("INSERT OR IGNORE INTO system(name,value)"+ " VALUES(?,?);");loadBooleanSetting(stmt, Settings.System.DIM_SCREEN,R.bool.def_dim_screen);loadIntegerSetting(stmt, Settings.System.SCREEN_OFF_TIMEOUT,R.integer.def_screen_off_timeout);// Set default cdma DTMF typeloadSetting(stmt, Settings.System.DTMF_TONE_TYPE_WHEN_DIALING, 0);// Set default hearing aidloadSetting(stmt, Settings.System.HEARING_AID, 0);// add for set default font// loadFractionSetting(stmt, Settings.System.FONT_SCALE,// R.fraction.def_font_size_scale, 1);loadSetting(stmt, Settings.System.FONT_SCALE, 1.3f);+ loadStringSetting(stmt, Settings.Secure.DISPLAY_DENSITY_FORCED,R.string.def_display_density);
