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：

    修改系统文字大小和framework/dimens内一致

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.java


 private 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 type
            loadSetting(stmt, Settings.System.DTMF_TONE_TYPE_WHEN_DIALING, 0);
            // Set default hearing aid
            loadSetting(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);
//.........
